基于MATLAB的Nakagami衰落信道仿真与分析

Analysis and simulation of Nakagami fading channel using MATLAB

由于Nakagami衰落能够表示实际中所遇到的大多数衰落环境,因而对基于MATLAB的Nakaga-mi衰落信道进行了分析,并对它的统计特性进行了仿真,包括接收信号的复包络模拟和在具有最大比合并分集下的电平通过率及平均衰落持续时间的性能分析。重点在于理解和建立采用MATLAB进行信道仿真的方法及对Nakagami衰落信道本身统计特性的理解。

Because Nakagami fading can represent the wide range of commonly encountered fading condition, simulation and analysis of the statistical characterizstics of the Nakagami fading channel using MATLAB are made including simulation of the complex envelope of received signal,and simulation the level crossing rates and average fading durations on the maximal-ratio combining diversity. The important issue in this paper focuses on the method of fading channel simulation using MATLAB and the comprehension of the Nakagami channel's statistical characterizstics.
