摘　　要：改进了一种产生Nakagami随机序列算法,讨论了Nakagami衰落信道的统计特性,其中包括接收信号的包络统计特性和3种分集合并方式下的电平交叉率、平均衰落延时,然后利用仿真模型对各种统计特性进行仿真和分析,并与理论分析结果进行了比较。An improved algorithm for generating Nakagami random sequence is proposed. The statistical properties of Nakagarni fading channels are studied, including the envelope of the received signal and the level crossing rates （LCR） and average fade durations （AFD） for three diversity combining techniques. Simulation is made by using simulation model of Nakagami, and then the simulation result is compared with theoretical result.
