摘要
Abstract
PE Model has been widely applied to the research on radio propagation characteristic predication, and is also an important method of solving problems in radio propagation. The error caused by the treatment of pseudo-differential operator Q in the deduction process of PE mode is analyzed. The analysis result proves that PE model is of high calculation accuracy when the radio propagation with small elevation angel is predicted. The computer simulation for theoretical model of radio propagation loss based on PE model was performed) and then the theoretically-calculated value of radio propagation loss was got. In comparison with the detected data, the correctness that employs PE model to predicat the radio propagation character-istics is proved. Also, this article analyzes and gives out the reasons why the calculated value of the theoretical model is smal-ler than actual detected one.关键词
