Abstract

The invention discloses a prediction method for electromagnetic radiation of a CDMA base station. The method includes the following steps of establishing a prediction expression of electromagnetic radiation values of different point locations around the CDMA base station, wherein the expression contains the two factors of an infinite distance decrement rate and an initial decrement rate; furthermore, through base station electromagnetic-radiation historical-value of the different point locations around the CDMA base station, inputting the established prediction expression for training, determining error value parameters of the expression, and through the determined prediction expression, predicting electromagnetic radiation conditions of the different point locations of the CDMA base station. By means of the method, the electromagnetic radiation prediction mode of the CDMA base station is analyzed, and the two factors of the infinite distance decrement rate and initial decrement rate of electromagnetic radiation are considered; the method can efficiently and accurately predict the electromagnetic radiation distribution conditions of the different point locations of the CDMA base station, and has certain social benefits.

Description

technical field [0001] The invention relates to a method for predicting electromagnetic radiation of a CDMA base station. Background technique [0002] The intensity of electromagnetic radiation around the base station will continue to decrease with the increase of distance, and this change has certain characteristics and regularity. At present, the published literature and patents have not provided an efficient and accurate prediction model based on the characteristics of this change. , which is used to evaluate the variation of base station electromagnetic radiation with distance. [0003] Aiming at the deficiencies in the prior art, this patent establishes an expression for predicting the electromagnetic radiation value at different points around the CDMA base station. This expression includes two factors: the infinite distance decline rate and the initial decline rate. The historical value of electromagnetic radiation of the base station, input the established predictio...
