一个关于PCA降维的小例子，用matlab编写(PCA matlab)

MUSIC(Multiple Signal Classification)算法是Schmidt在1979年首先提出的，是早期经典的超分辨率DOA估计方法(即超瑞利限的方法)，属特征结构的子空间方法。(MUSIC (Multiple Signal Classification) algorithm is Schmidt first proposed in 1979, is an early classic super-resolution DOA estimation methods (ie, super-Rayleigh limit of the method), is a characteristic structure of the sub-space method.)

说明：  工具箱包含大量执行时域分析的算法，特别用于二次能量分布的情形，这些算法通过分配问题得到改进。希望能对大家有所帮助！(The toolbox contains numerous algorithms performing time-frequency analysis with a special emphasis on quadratic energy distributions of the Cohen and affine classes, and their version enhanced by the reassignment method.)

svpwm 模型实例，希望大家给出意见 (SVPWM model as an example, hope everyone give advice )

通信系统的仿真,卷积码是纠错码的一种,可以用于数字电视,手机等通信领域,本例子给出了基于matlab的程序，卷积码BPSK调制。(Simulation of communication systems, convolutional code is an error-correcting code can be used for digital television, mobile phones and other communications, the examples given based on the matlab program convolution code BPSK modulation.)

It is SM algorithm code which exists IQ imbalance. You can modify IQ imbalance parameter, channel model and modulation.

Fast Visibility Restoration from a single Color or Gray level Image source code

图像的几何操作：图像旋转，图像剪切，包括旋转角度。(Geometric image operations: image rotation, image shearing, including rotation.)

说明：  简单实用的matlab程序实例，大家有什么不懂的可以问我啊(Matlab procedure simple and practical examples, we can not understand what asked me ah)

是最基本的ldpc matlab程序，简单易学，可以经过改编成为ldpc基础(Is the most basic ldpc matlab program)
