有关于OFDM系统的在AWGN信道下(BPSK调制)的信噪比分析.

% Gives delay to input signal

function [iout,qout] = delay( idata, qdata , nsamp , idel )

iout=zeros(1,nsamp);
qout=zeros(1,nsamp);

if idel ~= 0 
  iout(1:idel) = zeros(1,idel);
  qout(1:idel) = zeros(1,idel);
end

iout(idel+1:nsamp) = idata(1:nsamp-idel);
qout(idel+1:nsamp) = qdata(1:nsamp-idel);
