说明：  这本书用matlab仿真了数字通信原理中的各部分，很有参考价值(This book matlab simulation of digital communication with the various parts of the principle, a good reference)

用matlab实现画出基本概率密度函数的相位，能量，实部等的功能(Using matlab to achieve basic probability density function of the draw phase, energy, real function of such)

基于频带方差法的语音信号端点检测的matlab程序，可以用于语音信号的处理(Variance method based band voice signal endpoint detection matlab program that can be used to handle voice signals)

这是我自己编写的一个改进的经验模态分解EEMD的源码，希望大家能用上(This is what I have written an improved empirical mode decomposition EEMD source code, I hope everyone can be on)

说明：  函数程序,用于刚学习MATLAB的初学者熟悉软件用(Functional programming, MATLAB for beginners just learning to use familiar software)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)
