瑞丽衰落和莱斯衰落的对比
瑞利衰落(Rayleigh Fading):在无线通信信道中,由于信号进行多径传播达到接收点处的场强来自不同传播的路径,各条路径延时时间是不同的,而各个方向分量波的叠加,又产生了驻波场强,从而形成信号快衰落称为瑞利衰落。瑞利衰落属于小尺度的衰落效应,它总是叠加于如阴影、衰减等大尺度衰落效应上。(rice fading and rayleigh fading)

在无线通信体系中,由于开放的通信信道条件,卫星通信系统中通信链路容易受到平均大气条件的影响,尤其是采用Ka波段的高频信号的系统,容易受到降雨造成的雨衰影响,严重影响了系统的有效性和可靠性。(In a wireless communication system, the communication channel open, average atmospheric conditions vulnerable to the communication link in satellite communication system, especially the system of high frequency signal using Ka band, vulnerable to the influence of rain attenuation caused by rainfall, seriously affect the validity and reliability of the system. In digital systems, channel coding is often used to improve reliability, while modulation is used to ensure effectiveness. Low order modulation and large redundancy coding are adopted to improve the reliability.)
