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-SCDMA mobile communication base station electromagnetic radiation environmental impact prediction model [J]. Radiation Research and Radiation Technology Acta Sinica, 2015, 33(4):59-64.) On the basis of the electromagnetic wave propagation formula in free space, the TD-SCDMA signal duty cycle is introduced to predict the average electromagnetic radiation intensity, which improves the average electromagnetic radiation prediction to a certain extent The accuracy of the result, however, this method is calculated by the maximum duty cycle of the TD-SCDMA signal, and there is a large deviation from the actual duty cycle
