二、循环码简介

1 循环码概念
循环性是指任意码组循环移位后仍然是该编码中的一个码组
多项式表示法
一般情况

2 循环码的运算
2.1 整数的按模运算

2.2 码多项式的按模运算

2.3 循环码的数学表示法

2.4 循环码的生成

2.5 寻求码生成多项式

三、部分源代码

function varargout = xinxilun(varargin)
% XINXILUN MATLAB code for xinxilun.fig
%      XINXILUN, by itself, creates a new XINXILUN or raises the existing
%      singleton*.
%
%      H = XINXILUN returns the handle to a new XINXILUN or the handle to
%      the existing singleton*.
%
%      XINXILUN('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in XINXILUN.M with the given input arguments.
%
%      XINXILUN('Property','Value',...) creates a new XINXILUN or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before xinxilun_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to xinxilun_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
