matlab 编的瑞利信道仿真源码，对研究信道很有用(hgajdjkjhakhdkhakjlkjlka)

我国数字电视地面国标以及手机电视国标都采用了LDPC编码，本程序是LDPC的Matlab便解码实现，程序中附有说明，结构简洁，是了解LDPC原理和应用的最佳实例。(China Digital Television Terrestrial GB GB, as well as mobile TV using the LDPC codes, this procedure is LDPC decoding of Matlab will be realized, accompanied by a process of structural simplicity, is to understand the principle and application of LDPC best examples.)

在自适应控制中，用Matlab算法实现广义最小方差自校正控制（直接算法）(In adaptive control, using Matlab algorithm generalized minimum variance self-tuning control (direct algorithm))

说明：  matlab 遗传算法求解tsp，有详细的交叉，变异说明，适合初学者(matlab genetic algorithm tsp, detailed crossover, mutation description, suitable for beginners)

实用图像处理教程，是这方面的经典教程，适合通信的同学继续学习(Practical image processing tutorial, this classic guide for communication students continue to learn)

以r=6 1 103F为基础，抽取出其他m序列，在生成的m序列集中，寻找出m序列优选对，确定优选对数量，并画出它们自相关和互相关函数图形；(Based on the r = 6 1 103 f, extract other m sequence, concentrated in the generated m sequence, selection to find the m sequence, determine the optimum number of, and draw them autocorrelation and cross-correlation function graph )

说明：  实现三电平整流功能，相对于两电平，电平数更多，谐波更小(Achieve three-level rectification function, with more levels and less harmonics than two levels)

说明：  EMD matlab实现代码，可以直接用。经验模态分解（Empirical Mode Decomposition，EMD）是由 Huang等人于1998年提出的一种针对非线性、非平稳信号的自适应信号分解算法。(Empirical Mode Decomposition (EMD) is an adaptive signal decomposition algorithm for non-linear and non-stationary signals proposed by Huang et al. in 1998.)

finds the ratio between number of local extrema of a signal (vector) to the size of the signal (vector)

this is a simple function for convert into Cartesian to polar coordinates and adding two functions
