移动无线信道脉冲响应的计算机模拟

Computer Simulation of Impulse Response for Mobile Radio Channel

根据移动通信多径传播的一般化模型,模拟产生了移动无线信道的复值脉冲响应函数,模拟结果自然地反映了信道的衰落相关性,通过调整四个参数,可描述瑞利、Rice或其它形式的衰落信道,利用模拟结果分折数字通信中由于多径衰落引起的突发误码分布已取得成效。

According to a general multipath propagation model of land mobile radio communication, a simulation method for the mobile radio channel with the complex-valued impulse response is presented. The fading correlation is naturally contained in the simulation results. By using four adjustable parameters, the fading distribution of different sorts that may be Rayleigh, Rice or other fading modes can be discribed Some progress has been made in application of this method to the analysis of burst error rate caused by the multipath fading.
