摘要
小尺度衰落中的瑞利衰落和莱斯衰落是2种最为常见的无线接入信道衰落。从工程设计角度出发,重点分析了莱斯和瑞利信道条件下的2个重要指标——衰落深度和衰落速度,推导了相应的计算公式,特别是莱斯和瑞利信道条件下的衰落中值进行分析和计算。给出了在瑞利和不同莱斯因子条件下的PSK误码性能,为进行多径衰落无线接入信道的系统工程设计提供了参考。
In Multipath Fading,Rayleigh Fading and Rice Fading are two kinds of common wireless access propagation loss.From engineering design,this paper analyzes two important specifications in conditions of Rice Fading and Rayleigh Fading--rapidity of fading and depth of fading,derives corresponding equation,and gives the PSK performance analysis in condition of Rayleigh and different rice factor.Providing valuable reference for engineering design of Multipath Fading and Wireless Access Channels.
