第四版prokias著的数字通信配套matlab之第2章(source code(matlab )for prokias Digital Communication (4th edition))

说明：  主成分分析算法，用于建立主成分分析模型，采用累计贡献率的方法(pca )

基于压缩感知的OMP算法，用于信号重建，适合初学者(Based on the compression perception OMP algorithm for signal reconstruction, suitable for beginners)

说明：  进退法是用来确定搜索区间（包含极小点的区间）的算法，其理论依据为：f(x) 为单谷函数（只有一个极小值），且[a,b]为其极小点的一个搜索区间，对于任意x1,x2∈[a,b] ，如果f(x1)<f(x2)，则[a,x2]为极小点的搜索区间，如果f(x1)>f(x2) ，则[x1,b] 为极小点的搜索区间。黄金分割求极值(In a method is used to determine the search interval (contain minimum point interval) algorithm)

主要介绍了matlab的一些简单的命令，和它的功能以及使用方式，非常适合初学者。(Matlab introduces some simple commands, and its features and use, ideal for beginners.)

Matlab中由两个均匀分布随机变量产生高斯白噪声，以及自相关函数和功率谱图(Matlab by two uniformly distributed random variables have a Gaussian white noise, and the autocorrelation function and power spectrum)

数字信号处理综合设计 利用windows下的录音机录制一段自己的话音，时间控制在1秒左右；并对语音信号进行采样，理解采样频率、采样位数等概念。(Digital signal processing integrated design Using Windows, making a video recorder under his voice, time control in 1 seconds And the voice signal sampling frequency sampling, understand concepts, sampling digits. )

一段图像处理matlab代码，对于图像处理很有用哦。。。。。(A matlab image processing code, for image processing is very useful oh.....)

4) 创建一个名为Complex的类，进行复数的算术运算。复数的形式为： realpart+imaginarypart*i 用浮点变量表示类的private数据。提供构造函数，能够对所声明的该类对象进行初始化。在不提供初始化值的情况下，该构造函数应包含默认值。针对以下功能，分别提供一个public成员函数。 （1）两个复数相加； （2）两个复数相减 （3）用（a, b）的形式打印复数，其中a为实部，b为虚部。 (4) Create a class called Complex, and perform complex arithmetic operations. Plural form: realpart+imaginarypart* i said private data class with floating point variables. Provide a constructor, the object can be declared for the class is initialized. In the case do not provide initialization values, the constructor should contain default values. For the following functions, which provide a public member function. (A) two complex numbers (2) the subtraction of two complex (3) (a, b) in the form of plural printing, where a is the real part, b is the imaginary part.)

文件中的程序是蚁群算法在最短路中的应用，稍加扩展即可应用于机器人路径规划。(File in is the procedure ant colony algorithm in most short-circuit the application of, a little expansion can be applied to robot path planning.)
