摘要

考虑了rici和Nakagami-m衰落信道的统计特性，对其频率选择性衰落特性进行了统计分析。我们使用了Durgin提出的一种新的解析型多径形状因子，极大地简化了对rici和Nakagami-m衰落信道的描述。三个形状因子分别是角扩展、角收缩和最大衰落的方位方向。分析了接收信号在rici和Nakagami-m多径衰落信道中的一阶和二阶统计量。在形状因子理论中，空间单位自协方差和相干距离都使用解析表达式。

Statistical analysis of Rician and Nakagami-m fading channel using multipath Shape factors

Statistical characteristics of Rician and Nakagami-m fading channel are considered which develops the statistical analysis to characterize the frequency-selective fading properties. We use a new analytical multipath shape factors proposed by Durgin which greatly simplifies the description of Rician and Nakagami-m fading channel. The three shape factors are angular spread, angular constriction and azimuthal direction of maximum fading. The first-order and second-order statistics of received signal fluctuations in Rician and Nakagami-m multipath fading channel are analyzed. Analytical expressions for spatial unit autocovariance and coherence distance are both used in the shape factor theory.
