包含大量的MATLAB使用技巧,非常实用(Contains a large number of MATLAB tips, very useful)

用蒙特卡罗仿真研究一个通信系统的误比特率BER。假设通信系统满足条件：信源输出的数据符号是相互独立和等概的；在发射机中没有进行脉冲形成；信道是AWGN信道(Using Monte Carlo simulation of a communication system bit error rate BER. Suppose communications systems to meet the conditions: the data source output symbols are independent, and so almost the no pulse in the transmitter in the form channel is AWGN channel)

此程序可以解决pca问题，开发环境是matlab，希望对大家有帮助(This program can solve the problem pca, development environment is matlab, hope to help)

第七章 GUIDE入门 7.1 概述 7.2 图形句柄入门 7.3 GUIDE工具入门 7.4 创建图形用户界面外观 7.5 图形用户界面编程 7.6 常用的图形界面函数 7.7 本章小结 (Chapter VII GUIDE overview 7.2 Introduction 7.1 Introduction 7.3 GUIDE handle graphics tools to create entry-7.4 Appearance 7.5 graphical user interface graphical user interface programming 7.6 graphical interface function commonly used in this chapter 7.7 Summary)

说明：  行向量绘图，在matlab中对于含有大量的数据，单独在一张静态的图上是显示效果是很不理想的，这个程序实现了在matlab中以示波器的形式动态的显示器波形图(Row vector graphics in matlab in containing a large amount of data, alone in a static chart is to show the effect is not ideal, the realization of this procedure in matlab in the form of oscilloscope waveform display dynamic)

包含多种噪声谱估计算法用于语音增强，采用的是标准谱减法，主要用于对各种噪声谱估计算法对比，详见readme.txt(Ppls spectral subtraction noise spectrum estimation, mainly used to compare the performance of different noise spectrum estimation algorithms, including Martin s minimum tracking algorithm, Minimum controlled recursive average algorithm (Cohen), variant of Minimum controlled recursive average algorithm, improved Minimum controlled recursive average algorithm (Cohen ), continuous spectral minimum tracking (Doblinger), weighted spectral average (Hirsch & Ehrilcher), connected frequency regions (Sorensen & Andersen). See readme.txt inside)

用matalb来模拟排队论中的模型，M/M/n+M(simuation on ErlangA model)

QPSK BPSK qam的AWGN和瑞利信道的生成和仿真(QPSK BPSK qam of AWGN and Rayleigh Road, generation and simulation)

该文件是一个matlab程序，该程序是用来求出一个二值图像的面积，已经检验运行成功！(The file is a matlab program that is used to derive a binary image of the area, has been tested to run successfully!)

希尔伯特黄变换中的第一步EMD的matlab代码，希望对大家有用。(Hilbert-Huang transform in MATLAB code for the first step of EMD, hope useful to everybody)
