摘要
建立了Rice衰落信道的仿真模型 ,讨论了Rice衰落信道的统计特性 ,推导了电平交叉率 (LCR)和平均衰落延时 (ADF)的理论表达式 ,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比较。
In this paper,simulation model of Rice fading channels is proposed.The statistical properties of Rice fading channels are investigated,such as Level crossing rate (LCR) and average duration of fades (ADF) can be derived.Then the LCR and ADF of the simulation model of Rice fading channels are simulated,and compared to corresponding theoretical result.
