ofdm_EM_channel OFDM信道估计源代码

function [ofdm_dSource_pilot,pilotNUM] = addpilot_em(ofdm_Source,Dist)%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
