摘　　要：产生统计独立的多径相关瑞利信道是无线信道仿真的一个基本问题.Jakes模型得到了广泛应 用,但它在统计独立性方面还存在一些问题.该文提出一种新的相关瑞利信道的数学模型.理论分析和仿真 比较表明它在计算复杂度和统计独立性方面比最初的Jakes模型及其近来发现的改进模型更加简单有效.It is a basic problem for the simulation of correlated Rayleigh fading to produce the multiple independent Rayleigh fading waveforms. Jakes model has been widely accepted, but it has major shortcoming in the statistical independence. A new math model of multiple independent correlated Rayleigh fading is put forward. Both theory and simulation show that it is superior to the original Jakes model and its modified models that have been discovered in the aspects of the computation complexity and statistical independence.

关 键 词：相关瑞利信道 无线衰落信道仿真 JAKES模型
