OFDM信道估计源代码

OFDM信道估计源代码 matlab 好东西，给大家分享了

function [ofdm_dSource_pilotpilotNUM] = addpilot_em（ofdm_SourceDist）%ofdm_dSource表示发送信号，dist表示我把ofdm_dSource改为ofdm_Source
   sizeP = size（ofdm_Source）;
   pilotNUM = floor（sizeP（2）/Dist）;
   for i = 1:pilotNUM
      ofdm_dSource_pilot（:Dist*（i-1）+i） = ones（sizeP（1）1）;%这里就少了一列数据了
      ofdm_dSource_pilot（:Dist*（i-1）+i+1 : Dist*（i-1）+i+1 + Dist-1） = ofdm_Source（:Dist*（i-1）+1:Dist*（i-1）+1 + Dist -1）;
   end
   ofdm_dSource_pilot（:Dist*（i-1）+i+1+Dist-1:sizeP（2）+pilotNUM）=ofdm_Source（:Dist*i:sizeP（2））;%这一句是我加的，用来保证最后一个导频后面的也可以保留
