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