func_add_csi_err.m

基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.

function H = func_add_csi_err(h,N,flg_csi_err) 
H = fft(h,N,1);
if flg_csi_err == 1
    H = H.*10.^((randn(size(H)) + i*randn(size(H)))/sqrt(2)/10); 
    %g=10.^((10*log10(g_noCSI_Err)+randn(size(g_noCSI_Err)))/10);%/chEstErrorFactor;
end
