录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法和双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Section of their own voice recording signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and bilinear transformation design of filters, and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback voice signal Finally, the design of a signal processing system interface.)

数学积分方程的求解方法，包括线性和非线性，解析法和数值法(Mathematical integral equation methods, including linear and nonlinear, analytical method and numerical method)

做一个特征提取的模拟。功能良好。非常实用(To make a feature extraction simulation. Good function. Very useful)

使用log-map sova 进行turbo 并有完整(use log-map sova decode the turbo code)

以matlab撰写的遗传算法，可以解决工程问题的优化。验证功能良好。(Matlab code for genetic algorithms. )

说明：  Matlab demonstration script for DSB-AM modulation.

Given 2 subscripts, j & k, KronD will return 1 if j == k and 0 if j != k. A very simple function with only a single if-else statement. Saves a bit of typing when the Kronecker Delta is needed.

说明：  本教程提供了使用MATLAB的实践性指导，它基于MATLAB6.0版，内容由浅入深，特别是本书对每一条命令的使用格式都作了详细而又简单明了的说明，并配备了例题加以说明其用法，因此，对于初学者自学是很有帮助(The Guide provides practical guidance to the use of MATLAB, which is based on MATLAB6.0 edition, the content of easy-to-digest, especially the book on the use of each command formats are explained in detail and simple description and sample questions to be equipped with its usage, therefore, self-study is very helpful for beginners)

基于led数学模型的建立rgbled的光谱仿真模型程序(Led the establish rgbled of the mathematical model spectrum-based simulation model program)

MATLAB文件。《超宽带无线电基础》配套程序，第二章第3个例程。用于产生QPSK编码。(MATLAB file. Ultra-wideband radio base matching program, the first chapter of a routine. QPSK for generating code.)
