GMSK C语言实现其调制和解调，并提供了仿真程序(gmsk modulation——demodulation)

介绍小波的基本概念,并对图像进行压缩,消噪,增强,融合以及平滑处理.(introduced the basic concepts, as well as image compression, denoising, enhancement, integration and smooth handling.)

说明：  此程序是变型PID控制算法的仿真程序，采用了变速积分方法，系统偏差大时，积分作用应减小，反之应加强。变速积分可以根据系统误差大小改变积分速度，提高了系统品质。(this procedure is a change in the PID control algorithm simulation program using the variable integration method, the system deviation, the integral role should be reduced, on the contrary should be strengthened. Integral variable speed system error can change the size of integration of speed, quality of the system.)

直接序列扩频系统在白噪声环境下的仿真（信号采用升余弦滚降成形）(Direct sequence spread spectrum simulation white noise environment)

喷泉码中的LT码的程序，基于鲁棒孤波分布，有待完善(fountain code)

有限时域差分算法Matlab程序，用于计算场强分布。(finite time domain finite difference algorithm is used to calculate the field intensity distribution)

说明：  APF有源滤波器仿真，两电平，三相四线制，电力电子技术，matlab simulink(APF active filter simulation, two-level, three-phase four-wire system, power electronics technology, matlab simulink)

基本教学程序 通过这个程序可以掌握初步的matlab编程(Basic teaching procedures)

多源测试与信息融合证据理论作业,根据文献内容编写，用于北京航空航天大学多源测试与信息融合课程参考(Multi-source information fusion theory of evidence testing and operations)

Speaker recognition is the task of validating individual s identity using invariant features extracted from their voices print. Speaker recognition technology common applications include authentication, surveillance and forensic applications. This Paper investigates the performance of three automatic model selections based on Gaussian Mixture Model (GMM). These approaches are Bayesian information criterion (BIC), Bayesian Ying–Yang harmony empirical learning criterion (BYY-HEC) and Bayesian Ying–Yang harmony data smoothing learning criterion (BYY-HDS). Experimental evaluation of these methods is presented.
