进行Hilbert-Huang变换的源代码，可以对信号进行时频分析，非常好用

自己做的LCL滤波器matlab m文件(LCL filter)

this code is based upon LBP..

说明：  本资料系统讲解了随机信号的基础知识，对于以后信号处理的研究有一定的借鉴性。(The information system to explain the basics of random signals, signal processing for future research have certain reference.)

利用matlab语言实现的BP算法，很好用。(Using matlab language implementation of the BP algorithm, it just works.)

内附收集的几种ldpc代码（编码解码皆有），另有论文及书籍（pdf格式）(Containing a collection of several ldpc code (codec Jieyou), while papers and books (pdf format))

说明：  这是一个AWGN信道下，编译码仿真的C程序。本人已经用它产生数据绘制折线图！包含编码，译码，信道模拟，误码率计算 …… ,程序结构清晰，不复杂，适合与初学者来了解，基本通信流程！(This is an AWGN channel, the decoding simulation C program. I' ve used it to generate data to draw a line chart! Including encoding, decoding, channel simulation, bit error rate ... ..., the program structure clear, not complicated, for with the beginners to understand, the basic communication process!)

说明：  带约束算子的粒子群算法，用于matlab环境，对于搞研究的教师有很大帮助(Operator Constrained Particle Swarm Optimization for the matlab environment, engage in research for teachers are very helpful.)

说明：   该函数用于读取ecg信号，找到小波变换模极大序列,及按级给出概貌和细节的波形(This function is used to read the ecg signal sequence found on wavelet transform modulus maxima, and by level overview and details of the waveform is given)

求解线性不定方程组的一个基解（未知数个数大于方程个数），代码简单有效，可以利用该代码求出所有基解，从而得到不定方程组解得一般形式(A radical solution for solving linear equations uncertain (unknown number greater than the number of equations), the code is simple and effective, you can use the code to all base solution obtained, resulting in variable equations have the general form of the solution)
