Kind of releasable regenerated resources, therefore improve the utilization rate of frequency spectrum resource so that limited resource can maximum making full use of,
It is thus possible to alleviate the serious disparities between supply and demand existed between massive demand and the limited supply of future spectrum resource.Frequency spectrum occupancy rate
The maximally effective embodiment of frequency spectrum resource service condition being presently considered to be.The measurement result of frequency spectrum occupancy rate be by spectrum management,
Distribute, audit and recognize one of important evidence of radiotechnics application.
In prior art, the calculating of frequency spectrum occupancy rate is based on long measurement data, arranges 1 threshold level and carries out
Judgement calculates, and eventually forms the frequency range degree tables of data of each hour.
During realizing the present invention, inventor finds that prior art at least exists following deficiency:
During actual measurement, owing to being affected by external field environment, make an uproar difference in the end of each time period signal, so that
Obtain decision threshold also to differ；Differently configured, in the tables of data of frequency range degree, to each channel due to different frequency range channel
Degree indicate certain limitation.
Summary of the invention
The technical problem to be solved in the present invention is to provide the measuring method of a kind of frequency spectrum occupancy rate, improves frequency spectrum occupancy rate and surveys
The accuracy of amount, effectively reduces sampling number simultaneously, reduces the data volume measured, and graphically instant output spectrum
Degree information.
For reaching above-mentioned purpose, technical scheme is as follows:
The measuring method of a kind of frequency spectrum occupancy rate, comprises the following steps:
1) power of tested place tested frequency range radio signal monitored for a long time by receiver, and power is converted to field
By force；
The monitoring time is a time segment with a cycle time, and each sampled point in each time segment is by comparing
Method, find a maximum field intensity value, thus be field intensity value vector by the field intensity value matrix conversion in this time period, then
In field intensity value vector, by the method compared, find a field minimum intensity values, then on the basis of field minimum intensity values, add 5dB,
Thus form decision threshold, finally each field intensity value is compared with decision threshold, it is thus achieved that in " 0,1 " matrix, and " 0,1 " matrix
Each element be decision value.
2) carry out " 0,1 " matrix of same test each time segment of frequency range sequentially in time adding by row, it is thus achieved that
" judgement " matrix calculated for channel, frequency range degree；
3) all elements in " judgement " matrix is carried out weighted average by row, it is thus achieved that frequency range degree；By " judgement " matrix
In each column element be weighted averagely by row, it is thus achieved that each channel degree；Finally that result of calculation is the most defeated
Go out.
Preferably, described decision threshold is to monitor the field intensity value of signal as foundation with each time segment, field intensity value with sentence
Certainly thresholding compares, more than being " 1 " during decision threshold, less than being " 0 " during decision threshold.
Preferably, after described " 0,1 " matrix merges into " judgement " matrix, the row of matrix is that each channel is sentenced by each time point
Certainly value, matrix column is the decision value that the sampling each channel of frequency range is sampled every time.
Preferably, the calculating of each time period channel degree is by after the decision value summation of corresponding channel column, divided by
Total sampling number；The calculating of each time period frequency range degree is by the degree of corresponding each channel by rows, forms frequency
Road degree sequence, thus obtain frequency range degree.
By technique scheme, the invention has the beneficial effects as follows:
The present invention can effectively improve frequency spectrum occupancy rate measure accuracy, meanwhile, can be according to tested band channels
Configuring condition, effectively reduce sampling number, reduce the data volume measured.
