广义两射线衰落模型分析的矩生成函数方法

信息论 2020-04-02 v2 math.IT

摘要

我们分析了一类广义两射线 (GTR) 衰落信道,该信道由两个具有随机相位的视距 (LOS) 分量和一个漫射分量组成。我们推导了该模型信噪比 (SNR) 的矩生成函数 (MGF) 的闭式表达式,这极大地简化了其分析。该表达式源于观察到 GTR 衰落模型可以用条件底层 Rician 分布来表示。我们展示了该方法如何推导 GTR 衰落信道中感兴趣的统计量和性能指标的简单表达式,如衰落量、电平穿越率、符号误码率和遍历容量。我们还表明,考虑 LOS 分量之间相位差的更一般分布会对平均 SNR 产生影响。
