用小波函数进行分解与重构信号，通过重构信号在进行基音检测的运算(Wavelet function decomposition and reconstruction signal through the reconstructed signal during operation pitch detection)

BPSK与QPSK调制解调系统的Matlab仿真程序； 发送滤波器与接收滤波器均为根升余弦滚降滤波器； 信道噪声为加性高斯白噪声； 绘制BPSK与QPSK调制下的误码率与信噪比曲线图，并与理论曲线进行对比。 (BPSK and QPSK modulation and demodulation systems Matlab simulation program transmit and receive filters are root raised cosine filter roll-off filter channel noise is additive white Gaussian noise draw BER BPSK and QPSK modulation with a letter under noise ratio graph and compare with the theoretical curve.)

自然激励技术法，用互相关函数代替脉冲响应函数。(Natural excitation technique method using cross-correlation function instead of the impulse response function.)

IIR数字滤波器的特点是h(n)为无限长序列。设计的基本思想是：模拟系统与离散系统存在着互相模仿的理论基础，所以可以让数字滤波器的特性去模仿一个模拟滤波器的特性，得到数字滤波器的H(z)，H( )之间的变换关系。设计时，先设计一个模拟滤波器的传递函数 ，然后通过s变量与z变量之间的变换关系求出数字滤波器的系统函数H(z)。(IIR digital filter is characterized by h (n) for infinitely long sequence. The basic idea of the design are: analog systems and discrete systems there is the theoretical basis of mutual imitation, so you can make the characteristics of a digital filter to imitate the characteristics of an analog filters, digital filters are H (z), H () of the the relationship between the transformation. Design, first to design a simulation of the filter transfer function, s variables and z and then transform the relationship between variables derived digital filter system function H (z).)

对图像进行边缘检测，很简单的一个程序，对初学者很有用！(it detects the edge of the image,a very simple example and it is very useful for the beginner.)

Data Analysis，matlab数据分析教材，英文版本，是一本比较新的资料(Data Analysis, matlab data analysis textbook English versions, is a relatively new information)

有matlab各种实用程序300多个，涵盖信号及图像处理，优化，各种科学计算，简明易学(Matlab utilities have a variety of more than 300, covering the signal and image processing, optimization, scientific computing, concise easy to learn)

these are some of the matlab programs that are used to analyse and study the computer networks
