摘要

研究了具有选择组合分集接收机和三个微分集最大比组合分集接收机在相关伽玛阴影Nakagami-m多径衰落环境下工作的宏观分集系统。计算了微分集MRC接收机输出信号的矩产生函数(MGF)。利用这些公式，求出了宏分集SC接收机输出信号包络线MGF函数的封闭表达式。该结果可用于计算几种调制方案下宏分集系统的误码概率。数值结果显示了Nakagami-m严重度参数、Gamma阴影严重度参数和阴影相关系数对MGF的影响。

Moment generating function of macrodiversity system with three microdiversity MRC receivers in Gamma shadowed Nakagami-m fading channel

Macrodiversity system with selection combining diversity receiver and three microdiversity maximal ratio combining diversity receivers operating over correlated Gamma shadowed Nakagami-m multipath fading environment is considered. Moment generating function (MGF) of microdiversity MRC receivers output signals are calculated. By using these formulas, closed form expression for MGF function of macrodiversity SC receiver output signal envelope is evaluated. This result can be used for calculation the bit error probability of proposed macrodiversity system with several modulation schemes. Numerical results are presented graphically to show the influence of Nakagami-m severity parameter, Gamma shadowing severity parameter and correlation coefficient of shadowing on MGF.
