Referring to Fig. 1, Fig. 1 is the embodiment of the design method of channel forming wave filter in the embodiment of the present invention, including:
101st, N number of frequency that power industry can not use in target continuous frequency spectrum is determined.
In the present embodiment, it may be determined that N number of frequency that power industry can not use in continuous frequency spectrum, wherein, the target Continuous frequency spectrum be 223 into 235Mhz frequency spectrum resources any one section of continuous frequency spectrum resource, the N be positive integer more than 1.
It is it should be noted that above-mentioned continuous for any one section in 223 to 235Mhz frequency spectrum resources to target continuous frequency spectrum Frequency spectrum resource, can also be other frequency spectrum resources certainly, herein only with State Radio Regulatory Commission regulation 223~ Illustrated exemplified by the frequency range that 235MHz frequency ranges use as business such as remote measurement, remote control, data transfers, as long as determining that target is continuous Frequency spectrum is any one section of continuous frequency spectrum resource in the frequency spectrum resource that target industry can use, and is not limited specifically.
It should be noted that the distribution condition of the frequency in target continuous frequency spectrum has a variety of, illustrate separately below:
First, frequency all in target continuous frequency spectrum is allocated frequency.
When all frequencies in target continuous frequency spectrum are allocated frequency, target continuous frequency spectrum can be now traveled through In all frequencies, therefrom find out and be not yet assigned to N number of frequency that power industry uses, this is not yet assigned to the N that power industry uses Individual frequency is N number of frequency that power industry can not use in target continuous frequency spectrum, such as has 5 frequencies in target continuous frequency spectrum Point, wherein 3 are to distribute to the frequency that power industry uses, other 2 are the frequency for distributing to other industry, that is to say, that mesh 2 frequencies for distributing to other industry are the frequency that power industry can not use in mark continuous frequency spectrum.

101st, target continuous frequency spectrum is divided into N+ by the N number of frequency that can not be used according to power industry in target continuous frequency spectrum 1 frequency sub-band.
, can basis when it is determined that after power industry can not use in target continuous frequency spectrum N number of frequency in the present embodiment Target continuous frequency spectrum is divided into N+1 frequency sub-band by N number of frequency that power industry can not use in target continuous frequency spectrum.Illustrate It is bright, such as the frequency that 3 power industries can not use is there are in target continuous frequency spectrum, then target continuous frequency spectrum is divided into 4 Individual frequency sub-band, i.e., the frequency that can not be used using power industry in target continuous frequency spectrum divide as spaced points.
103rd, it is the individually designed lowpass digital filter of each frequency sub-band, to obtain N+1 lowpass digital filter.
Can be that each frequency sub-band is independent after target continuous frequency spectrum is divided into N+1 frequency sub-band in the present embodiment A lowpass digital filter is designed, to obtain N+1 lowpass digital filter.If target continuous frequency spectrum is divided into 3 sons Frequency range, it can be now the individually designed lowpass digital filter of each frequency sub-band, obtain 3 lowpass digital filters.
104th, N+1 group filter coefficients are determined according to N+1 lowpass digital filter.
In the present embodiment, the coefficient which kind of method to calculate N+1 group wave filters by is not limited herein, such as the wave filter Coefficient can be fulfiled ahead of schedule according to actual frequency point allocation in real target continuous frequency spectrum and be not take up hardware resource, can also be according to frequency After the service condition for composing perceptional function real-time update target continuous frequency spectrum intermediate-frequeney point, calculated by system self-adaption, do not limited specifically It is fixed, as long as every group of filter coefficient meets passband ripple and stopband attenuation, wherein, passband ripple refers in wave filter The difference of the maximum amplitude of passband and minimum amplitude in frequency response, the normal general passband ripple of wave filter is less than 1db, but also regards feelings Depending on condition, passband ripple can cause the signal amplitude size in passband to change, and require high system to some, ripple is smaller to be got over It is good.The exponent number of passband ripple and wave filter has a relation, and the bigger ripple of exponent number is smaller.Stopband attenuation:In the pass-band, there is part signal It is logical, part signal resistance, and the part hindered can not all block, only part is decayed, and is partly left behind, minimal attenuation describes The ability of signal of being obstructed is hindered, decay is bigger, then ability is better.
105th, merge after N+1 groups filter coefficient being carried out into numerical value frequency conversion, to obtain channel forming digital filter.
In the present embodiment, after N+1 group filter coefficients are determined, N+1 groups filter coefficient can be subjected to digital change Set of number filter coefficient is integrated into after frequency, then according to one group of numerical filters coefficient after integration be calculated logical Road is molded numerical filters.
In summary, can be first in the frequency spectrum for being defined as power industry and using in order to improve the utilization rate of frequency spectrum resource Optional one section of continuous frequency spectrum, determines N number of frequency that power industry can not use in the continuous frequency spectrum in resource, by the continuous frequency spectrum N+1 frequency sub-band is divided into, is the individually designed lowpass digital filter of each frequency sub-band, to obtain N+1 Low pass digital Wave filter, N+1 group filter coefficients are determined according to the N+1 lowpass digital filter, the N+1 groups filter coefficient is entered Merge after row digital frequency conversion, to obtain channel forming digital filter.In summary as can be seen that according in target continuous frequency spectrum Frequency resource distribution situation, the global design channel forming wave filter on continuous frequency spectrum, the channel forming wave filter is root Got according to the coefficient of lowpass digital filter individually designed in each frequency sub-band, therefore can be very good to match frequency spectrum resource Actual distribution situation, and hardware realization degree is low, and due to that need not set protection band in continuous frequency spectrum, therefore also improves Frequency spectrum resource utilization rate.
