Specific embodiment
Below with reference to embodiment, the invention will be further described, but not as a limitation of the invention.
Fig. 1 is please referred to, the present embodiment provides a kind of methods of day line traffic control for multiple input multiple output communications, for having
There is the electronic device of at least two antennas, the method is stored in the firmware or software in electronic device, and utilizes electronic device
The operating system of itself executes.Electronic device can be laptop, laptop computer, tablet computer, integrated computer, intelligence
TV, small base station or wireless router, but therefore the present invention does not limit.It the described method comprises the following steps.Firstly, carrying out
Step S110, electronic device simultaneously carries out wireless communication far end device using first antenna and the second antenna, that is, makes
Multiple-input and multiple-output (MIMO) transmission communication is realized at least two antennas.Using multiple-input and multiple-output (MIMO) transmission communication
Specification, e.g. 802.11n either existing forth generation mobile communication specification, or following the 5th third-generation mobile communication rule
Lattice.When the 5th third-generation mobile communication specification for being applied to future, the operating frequency of first antenna and the second antenna is that the 5th generation is mobile
The 3.5GHz frequency band or 6GHz frequency band of telecommunications metrics.
Then, step S120 is carried out, the even numbers of the first radiation regimes of even numbers and the second antenna according to first antenna
Second radiation regimes establish even numbers communication performance.The present invention is based on multiple input multiple output communications to be made to play better efficiency
The purpose of (promoted data rate), uses the antenna with even numbers radiation regimes, it may also be said to be using day line traffic control its grasp
Making state realization has multiple radiation patterns (radiation pattern that each mode of operation has is all different).Such as first antenna ATA
There is even numbers radiation regimes RB1, RB2, RB3 ... with even numbers radiation regimes RA1, RA2, RA3 ... RAm, the second antenna ATB
RBn.Electronic device selects a kind of radiation regimes (such as RA1) of first antenna ATA and selects the one of the second antenna in running
Kind of radiation regimes (such as RB1) to obtain a corresponding communication performance P11, may then continue with change first antenna ATA and
The radiation regimes of second antenna ATB, and the combination of being elected property, then available even numbers communication performance, such as can obtain
To communication performance P11, P12, P13 ... P1n, P21, P22, P23 ..., P2n ... etc., so that obtaining communication performance Pmn, in total
There is m multiplied by the result of n kind communication performance.The communication performance is usually presented with data rate.Also, change first antenna and second
The mode of the radiation regimes of antenna will be further illustrated in subsequent figure 2.
Then, step S130 is carried out, each communication is showed, the received signal strength indicator of first antenna is made
(RSSI) absolute value of absolute value and the received signal strength indicator of the second antenna subtracts each other, and obtains an absolute value differences.?
Each is exactly communicated into performance (P11 is so that Pmn) and has an absolute value differences.It, will be individual no matter communication environment is fine or not
It may be to be not easy it is contemplated that still working as first antenna that antenna, which changes influence of the radiation regimes for multiple-input and multiple-output data rate,
It is smaller with the difference of the received signal strength indicator of the second antenna, then it is (including steady to be more conducive to multiple-input and multiple-output data transmission
Fixed degree).Then, carry out step S140, the communication performance in, choose have the smallest absolute value differences communication show with
Multiple input multiple output communications as optimization.When there is the communication of the smallest absolute value differences to show for selection, no matter communication environment
Generally speaking quality is to indicate that first antenna and the second antenna all choose best or preferable radiation regimes simultaneously, most beneficial for
The transmission of multiple-input and multiple-output.Opposite, first antenna and the difference of the received signal strength indicator of the second antenna are bigger, for
May cause for multiple input multiple output communications more unstable transmission either data transmission rate variation floating be likely to compared with
It greatly, is all quite unfavorable for MIMO transmission.Step S140 of the present invention is to have selected have the smallest absolute value
The communication of difference is showed using the multiple input multiple output communications as optimization, is allowed at the same time using the logical of at least two antennas
In the case where believing framework, the difference on its absolute value of the received signal strength indicator of two or more antennas is accounted for, is borrowed
By the mode of selection lowest difference alienation, it is avoided as much as the unstability or uncertain parameters of transmission process, and is not necessary to pair
Complicated data operation processing is done in multiple-input and multiple-output matrix and can use more convenient (reduce cost and reduce operation time)
Mode propose prioritization scheme.Also, in the transmission process of multiple-input and multiple-output, if transmission environment or transmission range are changed
Become, step S120, S130 and S140 can also be made dynamically persistently to carry out, under conditions of avoiding influencing normal transmission state,
It can dynamically attempt to find out the more preferably communication performance for being suitable for situation at that time.
