音乐合成 内容：1) 自己朗诵一段文字，并录制成.wav 文件； 2) 利用 matlab，给这段录音添加背景音乐； 代码都嫁了注释(use matlab, add background music to the recording which you read a text )

This is a simple script two illustrate the concepts of Probability density function(pdf) cumulative density function (cdf). Two help pdfs are also included to understand the pdf and cdf concepts.

通过matlab，对mimo ofdm通信系统进行仿真，得出误码率与信噪比的关系(By matlab, for mimo ofdm communication system simulation, obtained BER and SNR relationship)

支持向量机的学习，简单但实用，推荐给各位哦(Studying supporting vector machine, is simple but pragmatic, recommendation is softly chanted by everybody)

matlab自编潮流程序，包括潮流，最优潮流，连续潮流等(self definite power flow program, include power flow, optimal power flow, continuous power flow)

一种混沌吸引子的演示程序，非常适合初学者研究和使用。 (A chaotic attractor of the demo program is very suitable for beginners to study and use.)

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).
