This is coding to analyse the rayleigh fading and its distribution.This is done through Matlab coding

说明：  常规OFDM系统容易导致ICI，为了消除ICI，在信号传输前进行编码，本系统为1/2PCC编码，提高系统效率。(Conventional OFDM system easily lead to ICI, is encoded in the signal before transmission, in order to eliminate ICI, this system for 1/2PCC encoding to improve system efficiency.)

设计一维纳滤波器 (1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n). (2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。 (A Wiener filter design (1) to produce three sets of observations: first generating a signal s (n) according to s (n) = as (n-1)+w (n), to add noise (20dB SNR, respectively , 10 dB, 6 dB), to obtain observational data x1 (n), x2 (n), x31 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)
