生成m序列与gold序列.docx

: .
m 序列
function [mseq] = m_sequence(fbconnection);
n = length(fbconnection);
N = 2An-1;
%m 序列的长度
register = [zeros(1,n - 1) 1];
% 定义移位寄存器的初始状态
mseq(1)= register(n);
%m 序列的第一个输出码元
for i = 2:N
newregister(1)= mod(sum(fbconnection.*register),2);
% 寄存器与反馈的模 2和
end
for j = 2:n,
end;
newregister( j)= register(j-1);
register = newregister;
mseq(i) = register(n);
% 移位后的寄存器
% 新的寄存器输出
clear all;
close all;
clc;
fbconnection=[0 0 1 0 1]; %输入本原多项式系数，从 C1 开始
m_sequence=m_sequence(fbconnection);
stem(m_sequence); %对 m 序列绘图
-可编辑修改 -
axis([0 35- ]);
grid on;

、生成gold序列
function goldseq = g_sequence(connection1,connection2);
msequencel = m_sequence(connection1); %生成第——个 m 序歹U
msequence2 = m_sequence(connection2); %生成第二个 m 序歹U
