陆地移动通信中多径传播的径数分布

Path-Number Distribution of Multipath Propagation in Land Mobile Radio Channel

本文分析了陆地移动通信中多径传播的径数的随机性,发现径数的变化服从线性生灭过程,导出了这一随机过程的分布律,所得结果用于多径时延分析和多径信道的模拟研究已取得成效。

Random characteristics of path number of multipath propagation for land mobile radio environment are analyzed. The variation in path number is found to be a linear Bir-th-and-Death process. Its distribution law is theoretically derived. Some progress has been made in application of this distribution to the analysis of multipath delay and the simulation of mobile radio channel.
