基于谱减法语音增强matlab程序，很好的去除噪声，得到增强的语音信号(Speech enhancement based on spectral subtraction matlab program, very good to remove noise, enhanced voice signal)

通过光速不变原理介绍相对论时间膨胀公式和长度收缩效应公式，并举例进行了说明。用曲线显示时间膨胀与物体速度的关系，显示长度收缩与物体速度的关系。(Through the principle of constancy of light, relativistic time dilation formula and length contraction effect formula, and examples are described. Curve shows the time dilation and the speed of the object, showing the length contraction and the speed of the object.)

遗传算法Matlab源代码,优化目标函数比较广泛，是常用的算法之一，同时也是学习其他算法的基础。(Genetic algorithm (ga) )

基于matlab的MPSK调制方式simulink仿真系统，系统中有录音模块、PCM编码、误码率计算等模块。(MPSK modulation mode based on the matlab simulink simulation system, the system of recording module, PCM coding, bit error rate calculation module, etc.)

Dinic method of maximum flow construction, for O(n^3), using pseudo-maximal flow construction by Malhotra - Kumar - Maheshvari. By Vitold Lipsky ( Combinatorics for programmers , 1988). Written by: Amir Tulegenov, 2009

信道编码模块。通过比较有无信道编码模块的不同系统误码率性能，感受信道编码技术对于提高系统性能的重要意义。打开“Channel_Coding_74.vi”打开程序框图并理解参与信道编码的整个数据流。(channel coding)

语音信号盲分离的一个号用的程序给大家共享，希望对大家有用(Blind separation of speech signals with a number of procedures to share, we hope to be useful)

GTRACK Track mouse position and show coordinates in figure title. GTRACK Activates GTRACK. Once it is active the mouse position is constantly tracked and printed on the figure title. A left-click will print the coordinates in the command line and store them.
