瑞利衰落信道，是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。这一信道模型能够描述由电离层和对流层反射的短波信道，以及建筑物密集的城市环境。(Rayleigh fading channels, the statistical model of a radio signal propagation environment. This model assumes that after the signal through the radio channel, the signal amplitude is random, ie, the " fading" and the envelope of the Rayleigh distribution. This channel model is able to describe the HF channel reflected by the ionosphere and troposphere, as well as building a dense urban environment.)

一整套OFDM系统的实现程序，基于梳状导频图案的OFDM系统估计，采用LS信道估计方法，和线性插值法，信道采用瑞丽多径信道。(A whole set of OFDM system, the implementation of the program of OFDM system based on comb pilot pattern, estimates using the LS channel estimation method, and the linear interpolation method, use ruili channel multipath channel. )
