ds_sp.m

程序对盲信号分离空时多用户检测器的仿真 但在程序中A用了随机矩阵

function spreaded_seq=ds_sp(seq_orig,pn_seq,len_seq,len_chip)
spreaded_seq=zeros(1,len_seq*len_chip);
for i=1:len_seq
    n_start=len_chip*(i-1)+1;
    n_end=len_chip*i;
    spreaded_seq(n_start:n_end)=seq_orig(i)*pn_seq;
   
    %spreaded_seq(n_start:n_end)=repeated_data(n_start:n_end).*pn_seq;
end
