一个非常经经典的WINDOWS下开发的书籍，欢迎大家来下载使用(a very good windows C develop book)

采用EM，期望最大方法，估计QPSK调制方式下的信噪比(Using EM, expectation maximization method to estimate the signal to noise ratio under QPSK modulation)

单极性PWM控制方式Simulink仿真，很简单，便于电力电子初学者学习，里面还加了一个模拟滤波器，也很简单，但想法非常重要(Unipolar PWM control Simulink simulation, very simple, easy for beginners to learn power electronics, which also added a simulated filter, is also very simple, but very important idea)

仿真一个从卫星到区域数据中心的下行链路（由一组6个载波构成），评估热噪声，交调（IM）失真、由滤波器引起的码间干扰（ISI）以及临频干扰对下行链路性能的影响。(Simulation of a regional data center from the satellite to the downlink (from a group of six carrier composition) to assess the thermal noise, intermodulation (IM) distortion, caused by the filter ISI (ISI) and adjacent channel interference on the downlink link performance.)

这是一个可执行的向量量化vector编码程序,希望对大家有所帮助(This is an executable vector encoding vector quantization process, I hope all of you to help)

i hope its useful for students

说明：  AD835的仿真模型,用matlab的工具箱，simulink搭建的(AD835 simulation model, using matlab toolbox, simulink built)

系统功率联合分配的matlab仿真算法,提高系统性能(Joint distribution power system matlab simulation algorithm)

蒙特卡罗方法在由已知分布的随机抽样中的应用(Monte Carlo method of random sampling from the known distribution of the application)

用matlab实现了2dpca算法，基于ORL人脸数据库，识别率较高(Matlab achieved with 2dpca algorithm, based on the ORL face database, the higher recognition rate)
