Technical field
This patent is related to a kind of base station electromagnetic radiation Interval evaluation method.
Background technology
Communication base station electromagnetic radiation has become an important factor for influencing social environment, in the electromagnetic radiation test to base station
In, base station electromagnetic radiation measuring value size constantly changes, and in addition there is also larger differences for measured value and electromagnetic radiation predicted value.
If in the electromagnetic radiation measuring of base station, tester has measured one group of electromagnetic radiation test data, while survey crew
Also have the base station electromagnetic radiation predicted value, but the two is not consistent, in this case, how the electromagnetic radiation to a base station
Size makes one and reasonably assesses particularly important, but at present in the document and patent having disclosed, there are no good sides
Method solves the problems, such as this.
Invention content
In order to solve the above technical problem, the present invention provides a kind of base station electromagnetic radiation Interval evaluation method, the patent energy
It is located at some interval value with certain probability Estimation communication base station electromagnetic radiation intensity, one can be made to base station electromagnetic radiation size
A relatively sharp assessment.
The present invention solves above-mentioned technical problem, and the technical scheme comprises the following steps：
1) by n electromagnetic radiation actual measured valueIt is compared with electromagnetic radiation predicted value E, obtains n electromagnetic radiation
Error value epsilonj, j=1,2,3 ..., n, and obtain the mean value U of n electromagnetic radiation actual measured value, wherein electromagnetic radiation predicted value
E, electromagnetic radiation error value epsilonj, mean value U calculate it is as follows：
P is the transmission power of base station in above formula (1), and unit W, G are antenna gain multiple, and r is antenna for base station and prediction
The distance between point, unit are rice, electromagnetic radiation actual measured valueElectromagnetic radiation predicted value E, mean value U and electromagnetic radiation
Error value epsilonjUnit be V/m；
2) the n electromagnetic radiation error value epsilon obtained according to step 1)j, j=1,2,3 ..., n pass through Matlab tools
It is fitted, fitting function is：
F (ε) in above formula (4) indicates that error amount is the probability of ε,For the mean value of error, σ is the variance of error, is passed through
MaTlab tools are fitted, and obtain the mean value of errorAnd variances sigma；
3) according to the mean value U of step 1) and the average value of step 2)Then base station electromagnetic radiation intensity has 95% probability to be
Positioned at sectionUnit is V/m.
