本程序在Matlab R2008的Simulink中实现了使用costas环对同步载波的提取，同时可提取出基带信号。(The program Matlab R2008 implements the use of Simulink to the synchronous carrier costas loop extraction, at the same time extract the baseband signal.)

简单的闭环连续的迭代学习控制模型，里面有自己搭的simulink模型，运行mian.m就能运行。(Simple closed-loop continuous iterative learning control model, which has its own simulink model ride, run mian.m be able to run.)

说明：  此为LDPC低密度校验码的编译码的原理与应用的详细介绍。包括各种信道模型下的仿真结果，有助于更好的学习通信系统的编译码过程的实现。(This is the LDPC coding and decoding LDPC codes principles and applications in detail. Including channel model simulation results, contribute to a better communication system of learning to achieve encoding and decoding process.)

R/S分形计算H指数，可以替换成自己的数据，很方便(R/S calculation of the fractal index H can be replaced by their own data, it is convenient)

用于支持向量回归分析 将数据分类 使用matlab运行环境(For support vector regression analysis of data classification using matlab runtime environment)

本程序主要用于DDS算法的验证,可以生成正弦波，占空比可调的方波，三角波；其中频率控制字可调，生成波形的频率也可调。(This procedure is mainly used for verification DDS algorithm, can generate sine wave with adjustable duty cycle square wave, triangle wave including adjustable frequency control word to generate adjustable frequency waveform.)

Histogram Matching(Image processing) the Algorithm Properties: - User can insert his/her desired histogram -user can input the desired Colored/Gray Scaled Image -Original/Enhanced Image Their histogram and transfer function are displayed -all the above again done by iterative Scheme (eq. 3.3-17 Gonzales Book)
