Problems solved by technology

Since the electromagnetic radiation of the TD-SCDMA communication base station is related to the signal duty cycle, the prediction results of the two methods of theoretical calculation and software simulation are not ideal. Therefore, it is necessary to find a fast and accurate prediction method for the electromagnetic radiation of the TD-SCDMA communication base station
[0003] For the prediction method of electromagnetic radiation of TD-SCDMA communication base station, the literature "TD-SCDMA Mobile Communication Base Station Electromagnetic Radiation Environmental Impact Prediction Model" (Yu Huiting. TD-S...

Abstract

The invention discloses a new electromagnetic radiation prediction method for a TD-SCDMA communication base station. The method comprises the steps of using a spectrum analyzer to measure maximum electromagnetic radiation intensity of a TD-SCDMA signal; building a service queuing model according to a channel resource distribution mode of a TD-SCDMA system, and computing probability distribution of the occupied downlink service slot; computing a duty ratio of the TD-SCDMA signal via the probability distribution of the occupied downlink service slot; and predicting the average electromagnetic radiation intensity of the TD-SCDMA communication base station based on the maximum electromagnetic radiation intensity and the duty ratio. According to the method provided by the invention, the service queuing model by analyzing the channel resource distribution mode of the TD-SCDMA system, the duty ratio of the transmitt4d signal is computed, and the average electromagnetic radiation intensity is predicted by using the maximum electromagnetic radiation intensity and the duty ratio of the TD-SCDMA signal. The method provided by the invention has a great reference value to build a TD-SCDMA communication base station, assess influence of an electromagnetic radiation environment and protect environment, and has excellent social benefit.

Description

technical field [0001] The invention relates to a method for predicting electromagnetic radiation of a TD-SCDMA communication base station. Background technique [0002] With the rapid development of the mobile communication industry, mobile operators have built a large number of communication base stations around our lives. While enjoying the convenience brought by communication base stations, people pay more and more attention to the impact of electromagnetic radiation of communication base stations. The main prediction methods for TD-SCDMA communication base station electromagnetic radiation are divided into three categories: theoretical calculation, software simulation and Field measurements. Because the electromagnetic radiation of TD-SCDMA communication base station is related to the signal duty cycle, the prediction results of the two methods of theoretical calculation and software simulation are not ideal. Therefore, it is necessary to find a fast and accurate predi...
