pn_generate.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 seq=pn_generate(connections)
m=length(connections);
len_chip=2^m-1;
registers=[zeros(1,m-1),1];
seq(1)=registers(m);
for i=2:len_chip
    new_reg_cont(1)=connections(1)*seq(i-1);
    for j=2:m
        new_reg_cont(j)=xor(registers(j-1),connections(j)*seq(i-1));
    end
    registers=new_reg_cont;
    seq(i)=registers(m);
end
