调制信号的波形及其功率谱。。。很好用。。(The modulated signal waveform and the power spectrum)

通过一个实例，学习libsvm在matlab中的使用方法，适合初学者。(One instance, learning to use libsvm in matlab, suitable for beginners.)

基于MATLAB技术的PWM发生器仿真模型。(PWM generator simulation model based on MATLAB technology.)

此例程可以用来进行希尔伯特变换，得到包络谱，利用差分公式得到瞬时频率(This routine can be used to carry out Hilbert transform, obtain envelope spectrum, and obtain instantaneous frequency by using difference formula)

直方图图像均衡化和规定划、以及加性噪声，如拖尾脉冲噪声，高斯脉冲噪声（自适应方法）、和椒盐噪声等等各种噪声的添加噪声和去除噪声的MATLAB代码(Histogram equalization and provisions of the planning image, and additive noise, such as trailing impulse noise, Gaussian pulse noise (adaptive approach), and salt and pepper noise, etc., add all the noise noise noise and remove the MATLAB code)

DSP Fixed point algorithms is used in this wwork. This work is very narrow and same time committement will be solved with new algorithms technique of econmic dispatch.

说明：  Optimization Example

用matlab实现模糊神经网络，在非线性系统中的应用(Achieved with matlab neural network, nonlinear system)

QC-LDPC码生成矩阵编程，围长为12，无4环(The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other algorithms. The program builds a Tanner graph by connecting groups of rows and columns. A connection is made if it does not form less than twelve-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms. )

The following attachment contains codes in Matlab for digital signal processing. In the file code is for digital signal convolution
