Description

Microwave communication equipment, system and method for eliminating the influence of phase jump

technical field

The invention relates to the communication field, in particular to a microwave communication device, a system and a method for eliminating the influence of phase jump in the microwave communication device.

Background technique

Microwave communication is the communication that uses electromagnetic waves with a frequency of 300M to 3GHz—microwave. Microwave communication does not require a solid medium, has a large capacity, good quality and can be transmitted to a long distance, so it is an important communication means of the national communication network, and is also generally applicable to various special communication networks.

How to eliminate the influence of phase jump is one of the most important issues in the design of microwave communication system (microwave system). Phase jump refers to the phase/frequency jump of microwave equipment (microwave communication equipment) during temperature changes. Phase jump will cause carrier mutation and bit error. If the phase jump is too large, it will even cause service interruption. Therefore, phase jump problem is the most fatal flaw of microwave products/equipment. The existing technology generally only starts from the possible factors that cause phase jumps, and takes relevant measures through repeated experiments to reduce the probability of phase jumps, for example: 1) Take insulation measures for the frequency source part so that the temperature does not change drastically with the ambient temperature ;2) The power supply filter and loop filter of the frequency source part avoid the use of capacitors with piezoelectric effect to reduce the phase jump caused by stress release; 3) The frequency source part is cleaned to reduce solder residue, etc. However, the occurrence of phase jumps is random and unpredictable, and these existing schemes can only reduce or avoid the factors that may cause phase jumps, and cannot monitor and deal with the phase jumps that have occurred, so they cannot Basically eliminate the effect of phase jump.

Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiments of the present invention provide microwave communication equipment, a system, and a method for eliminating the influence of phase jumps, which can fundamentally eliminate the influence of phase jumps, improve the ability of microwave communication equipment to resist phase jumps, and solve communication problems caused by microwave communication equipment due to phase jumps. There is a code error in the system.

Example 1:

An embodiment of the present invention provides a microwave communication device, as shown in Figure 1, the device includes: a frequency source 10, the local oscillator signal generated by the frequency source 10 and the baseband data signal are up-converted into a microwave signal and transmitted, or the received The microwave signal and the local oscillator signal generated by the frequency source 10 are down-converted into a baseband data signal (frequency conversion can be performed by a mixer), and the microwave communication equipment also includes:

Phase jump acquisition unit 20, used to collect phase jump information of frequency source 10;

The processing unit 30 is configured to perform phase correction on the baseband data signal according to the collected phase jump information, so as to eliminate the influence of the phase jump.

When the microwave communication equipment is working, the user equipment converts various information to be transmitted into baseband signals or converts the baseband signals into original information. The baseband signals to be sent cannot be directly transmitted in the wireless microwave channel, and the baseband signals must be converted into frequency band signals. In the form of digital modulation, the baseband signal to be sent is used to digitally modulate the carrier. The modulated signal (ie, the baseband data signal) is an intermediate frequency signal. To be transmitted by microwave, it needs to be converted into a microwave signal by upconversion. Similarly, the received microwave is down-converted into a baseband data signal, and then demodulated into a baseband signal. Among them, up-conversion is the process of mixing the intermediate frequency baseband data signal with a higher-frequency local oscillator signal; down-conversion is the inverse process of up-conversion, and the principle is similar, except that the local oscillator signal and the microwave signal are used. Just different combinations. In short, up and down conversion realizes frequency conversion between baseband data signal (IF signal) and microwave signal.

In this embodiment, it is considered that the part with the highest phase jump probability in the microwave link of the microwave communication equipment is the microwave local oscillator, that is, the frequency source 10. Taking the frequency source 10 shown in FIG. The devices with high jump probability are the reference oscillator 11 (Reference Oscillator, RO), the loop filter 12 (Loop Filter) and the voltage controlled oscillator 13 (Voltage Control Oscilltor, VCO). In order to eliminate the influence of phase jump, this embodiment transmits the phase jump analog signals generated by these devices back for configuration processing, so as to perform phase correction on the baseband data signal to eliminate the influence of phase jump. Besides, the frequency source 10 also includes a phase locked loop 14 (Phase Locking Loop, PLL).

It should be noted that the frequency source 10 in this embodiment may be a transmitting local oscillator or a receiving local oscillator.

In this embodiment, the phase jump acquisition unit 20 collects the phase jump information of the frequency source 10 and sends it back to the configuration processing unit 30 . The configuration processing unit 30 performs phase correction on the baseband data signal according to the phase jump information collected, fundamentally eliminates the influence of the phase jump, improves the ability of the microwave communication device to resist the phase jump, and solves the error in the communication system caused by the phase jump of the microwave communication device. code problem.

Specifically, as shown in FIG. 3, in a preferred implementation manner of this embodiment, the configuration processing unit 30 includes: an analog-to-digital conversion module 301 and an inversion module 302;

An analog-to-digital conversion module 301, configured to convert the collected phase jump information into a digital signal;

The inverting module 302 is configured to invert the digital signal to obtain a compensation signal, and superimpose the compensation signal on the baseband data signal. The waveform of the compensation signal is opposite to the phase jump waveform of the digital signal.

In this embodiment, the phase jump information collected from the frequency source 10 is an analog signal, and analog signal processing has the disadvantages of being difficult to achieve high precision, greatly affected by the environment, poor reliability, and inflexible. Therefore, in order to facilitate the phase jump To store and process the information, it is necessary to first convert the collected phase jump information into a digital signal through the analog-to-digital conversion module 301, and then input it into the inversion module 302 for processing to obtain a compensation signal.

The digital signal input to the phase inversion module 302 includes phase jump information, and the phase inversion module 302 performs an inverse transformation operation on the input digital signal, thereby obtaining a compensation signal for phase correction of the baseband data signal, wherein the inversion transformation operation is Refers to inverting the phase of the input signal by 180 degrees. The phase inversion module 302 is a module capable of inverting the phase of a signal. For example, optionally, the inverting module 302 may be a digital processor.

The phase inversion module 302 will be described in detail below with reference to the accompanying drawings: As shown in FIG. 4 , it is a schematic diagram of the principle of performing phase correction according to the returned phase jump information to eliminate the influence of the phase jump. Among them, A represents the phase jump waveform generated by the frequency source 10, which can be regarded as fitted by the digital signal output by the analog-to-digital conversion module 301; B represents the compensation signal output by the configuration processing unit 30, specifically in this embodiment. The compensation signal output by the inversion module 302 is fitted (the compensation signal is a digital signal).

The phase jump information (corresponding to the A waveform) collected by the phase jump acquisition unit 20 from the frequency source 10 is inversely converted by the configuration processing unit 30 (that is, the analog-to-digital conversion module 301 and the phase inversion module 302), and the output compensation signal ( Corresponding to the B waveform) is opposite to the phase jump waveform (corresponding to the A waveform) of the phase jump information. Therefore, superimposing the compensation signal of the reverse waveform on the baseband data signal can be used to offset the influence of the phase jump on the frequency (phase) mutation. The final effect Make the signal in the microwave link as if no phase jump occurs, as shown in C in Figure 4 .

It should be noted that in this embodiment, the backhaul processing can only be performed on the phase jumps that occur in the transmitting local oscillator, or the backhaul processing can be performed only on the phase jumps that occur in the receiving local oscillator. phase jump occurs.

The microwave communication device in this embodiment may be a microwave sending device, may also be a microwave receiving device, or may be a microwave sending and receiving device with integrated microwave sending and receiving functions.

The microwave communication device provided by the embodiment of the present invention returns the phase jump information, and then configures and processes the returned phase jump information to obtain the compensation signal of the reverse waveform, and then superimposes the compensation signal of the reverse waveform on the baseband data signal In order to eliminate the influence of phase jump, the phase jump can be monitored and processed from time to time, which fundamentally eliminates the influence of phase jump, thereby improving the anti-phase jump capability of microwave communication equipment and solving the communication problems caused by microwave communication equipment due to phase jump. A code error occurred in the system.

Example 2

The technical solution of the microwave communication equipment provided by the present invention is not only applicable to the indoor (or outdoor) all-in-one machine structure, but also applicable to the currently commonly used split structure. The microwave communication equipment with the split structure is used as an example for illustration below.

As shown in Figure 5, microwave communication equipment with a split structure, that is, the transceiver of the microwave communication equipment is outdoors (that is, the outdoor unit 200, Outdoor Unit, ODU), and the modem and baseband interfaces are indoors (that is, the indoor unit 100, Indoor Unit, IDU).

The indoor unit IDU100 mainly demodulates and digitizes the received microwave signal to decompose the required signal; at the same time, it also modulates the digital signal to be transmitted into a signal that can be transmitted. IDU100 mainly includes baseband and intermediate frequency (receiving and sending) parts, while ODU200 includes transmitter and receiver. The transmitter generally converts the frequency from 310MHz to 7GHz, and then filters and amplifies it to the antenna system; the receiver passes the signal received from the antenna system through a low-noise amplifier (LNA), and down-converts it to an intermediate frequency. (Generally 70MHz), after the intermediate frequency automatic gain control (IF AGC), it is transmitted to the IDU through the cable. The antenna feeder system is generally provided with a filter and an antenna for transmitting and receiving.

Wherein, the outdoor unit 200 in this embodiment includes a frequency source and a phase-hopping acquisition unit 20, the frequency source includes: a voltage-controlled oscillator (VCO) 13, the input terminal of the phase-hopping acquisition unit 20 and the voltage-controlled oscillator 13 connected to the input.

Specifically, the phase jump acquisition unit 20 includes: a capacitor 21, an amplifier 22 and a filter 23, one plate of the capacitor 21 is connected to the input end of the voltage-controlled oscillator 13, and the other plate is connected to the input end of the amplifier 22, The output of the amplifier 22 is connected to a filter 23 . Among them, the capacitor 21 is used to obtain the phase jump information of the frequency source 10 through capacitive coupling, the amplifier 22 is used to amplify the phase jump information, and the filter 23 is used to filter out the high frequency part of the phase jump information, and input it into the indoor unit IDU100. The indoor unit IDU100 in this embodiment includes: a configuration processing unit 30, the configuration processing unit 30 receives the phase jump information output by the phase jump acquisition unit 20, and performs phase correction on the baseband data signal according to the phase jump information collected, To eliminate the effect of phase jump.

As shown in Fig. 6, in another specific implementation manner, the indoor unit IDU100 in this embodiment includes: a digital processor 300 (Digital Signal Processing, DSP), and the configuration processing unit 20 is the digital processor 300 in the indoor unit IDU100 . Specifically, the phase jump information output by the filter 23 is sent back to the indoor unit 100 for processing by the digital processor 300 of the indoor unit 100 to perform phase correction on the baseband data signal to eliminate the influence of the phase jump. Optionally, the digital processor 300 itself has an analog-to-digital conversion function and a function of inverting a signal. Therefore, in other words, the digital processor 300 includes an analog-to-digital conversion module 301 and an inversion module 302 .

The indoor unit IDU100 also includes: a mixer 303 ; the compensation signal output by the inverting module 302 passes through the mixer 303 and is superimposed on the baseband data signal.

The working process of the microwave communication equipment in this embodiment to eliminate the influence of bit errors when the ODU microwave local oscillator (frequency source) generates a phase jump will be described in detail below with reference to the accompanying drawings 6-8.

If the transmitting local oscillator (transmitting frequency source) has a phase jump, then the transmission signal output by the outdoor unit ODU200 will have phase jump information, and the phase jump acquisition unit 20 collects the phase jump information from the input terminal of the voltage controlled oscillator 13. The transmission channel transmits the phase jump information to the indoor unit IDU100, and the IDU100 generates a compensation signal opposite to the phase jump waveform according to the phase jump waveform configuration (completed by the phase inversion module 302 of DSP300), and then superimposes the obtained compensation signal on the baseband data signal. Wherein, the compensation signal can be superimposed on the baseband data signal through the mixer 303 .

Then, the phase-hopping waveform sends the useful signal and the phase-hopping inverse waveform (that is, the baseband data signal including the compensation signal) to the ODU200 and the local oscillator signal generated by the frequency source. After the local oscillator signal is mixed, it is corrected to eliminate the transmission local oscillator. In this way, through the ODU200’s transmission channel, space transmission and ODU200’s receiving channel, the corrected useful signal is transmitted to the receiving end IDU100, so that the receiving end IDU100 can normally demodulate the useful signal without causing communication errors. As shown above with reference to FIG. 7 and FIG. 8 , the useful information in the figure, that is, the information to be transmitted, is included in the useful signal; the phase jump information is included in the phase jump waveform.

To put it simply, in the ODU200, the baseband data signal and the local oscillator signal generated by the frequency source synthesize the microwave transmission signal, and the baseband data signal in this embodiment contains a compensation signal, and the waveform of the compensation signal is the same as the generated phase jump waveform On the contrary, the influence of the phase jump of the transmitting local oscillator is thereby offset, and thus, the influence of the phase jump of the transmitting local oscillator on the final microwave transmitting signal can be reduced.

If the receiving local oscillator (receiving frequency source) of the ODU200 has a phase jump, it is transmitted to the IDU100 through the phase jump return channel, and the IDU100 generates a compensation signal opposite to the phase jump waveform according to the configuration of the phase jump waveform, and then superimposes the obtained compensation signal on the baseband data signal. Since the phase jump of the receiving local oscillator will affect the received useful signal, when the IDU100 demodulates the useful signal, the superimposed compensation signal will offset the frequency (phase) mutation caused by the receiving phase jump, so that the normal demodulation of the useful signal will not generate Communication errors.

The microwave communication equipment with a split structure provided in this embodiment can monitor and process phase jumps all the time, fundamentally eliminate the influence of phase jumps, thereby improving the anti-phase jump capability of microwave communication equipment and solving the problem of microwave communication equipment Bit errors in communication systems due to phase jumps

Further, as shown in FIG. 9 , the present invention also provides a microwave communication system, including any microwave communication device described in Embodiments 1 and 2. It can pre-cancel the frequency (phase) mutation caused by the phase jump that has occurred, and the IDU can demodulate the signal normally, eliminating the impact of bit errors caused by the entire system.
