关于通信基本原理的仿真

function [mseq]= m_sequence(fbconnection)

%fbconnection=[0 1 0 0 1];
n = length(fbconnection);
N = 2^n - 1;
register =[zeros(1,n-1) 1];%定义移位寄存器的初始状态
mseq(1)= register(n);
for k=2:N
    newregister(1)= mod(sum(fbconnection.*register),2);
    for l=2:n
        newregister(l)= register(l-1);
    end
    register = newregister;
    mseq(k)= register(n);
end
