m_seq.m

由MLS产生Gold码序列,<通信原理与Matlab仿真>经典范例

function [seq]=m_seq(connections);

m=length(connections);  % m 位反馈移位寄存器长度
L=2^m-1;                % m序列长度
registers=[zeros(1,m-1) 1];
seq(1)=registers(m);
for i=2:L
    reg_cont(1)=connections(1)*seq(i-1);
    for j=2:m
        reg_cont(j)=registers(j-1)+connections(j)*seq(i-1);
    end
    registers=reg_cont;
    seq(i)=registers(m);
end
