说明：  光学夫朗和费衍射现象模拟Matlab源代码 (Optical phenomenon of Fraunhofer diffraction simulation Matlab source code)

在qpsk系统分析中进行蒙特卡洛性能仿真 其中信道信道模型为高斯信道(The montecarlo simulation performance )

基于MATLAB语音信号采集与分析加上高频噪声并去噪声源程序(the source program of voice signal acquisition and analysis with high-frequency noise based on matlab.)

matlab编写的频域分解法程序，可以在此基础上进行改进.(matlab prepared frequency domain decomposition procedures can be improved on this basis.)

是国外经典matlab教材的翻译本，内容详实，有大量例题，对于要进行数学建模的人大有裨益，所有程序都是经过验证的。(Is the translation of classic matlab materials abroad this informative, a large number of examples are proven.)

这个是一个SVM分类器，可以再行人检测时用来分类训练样本，再MATLAB中直接调用(This is an SVM classifier, when pedestrian detection can be used to classify the training sample, and then directly call MATLAB)

基于MATLAB的一阶和二阶模型辨识程序（加入1 的白噪声）仿真后得出辨识以及实际阶跃图形(MATLAB-based first-order model identification procedures (adding 1 white noise) simulation based on the identification of the actual step graphics)

软件程序按照发射端所掌握的各用户信道状态信息的程度共分为两部分：即完整信道状态信息(CSIT)和部分信道状态信息(CSIP)。其中，每一部分都包括预编码(precoding)和用户调度(scheduling) 在CSIT中，precoding又按照各用户的数据流数分为单数据流和多数据流两种情况。在每种情况下，首先考察了不同预编码算法的性能表现，包括两种ZF、MMSE、SINR、SLNR。之后又考察了功率分配算法的性能表现（文件名中含有PD表明其含有功率分配的过程）。按照不同指标进行功率分配的，在文件名中进行了区分，如PD_CN代表以信道范数为参考指标进行功率分配。Scheduling部分首先观察了RoundRobin、MaxH和MMSLNR三种算法的性能对比。之后在Kc和Round部分分别观察了不同预选用户数和不同最大替换轮数下MMSLNR算法的表现。 在CSIP中，只对各用户单数据流的情况进行了仿真。采用的预编码算法主要有DSLNR（即直接运用CSIT下的预编码算法）、ESLNR（即对SLNR进行均值计算的，在CSIP中，引入均值计算的与SLNR有关的算法，其文件名中都有modified以示区别）、EMMSE（即陈明老师那边的那篇文章中的预编码算法）。Scheduling中也只是简单的观察了RoundRobin、MaxH、DMMSLNR和EMMSLNR（前者没有均值计算，后者有）的性能对比。(The degree of channel state information for each user software program in accordance with the master transmitter consists of two parts : the complete channel state information (CSIT) and partial channel state information (CSIP). Wherein , each of which comprises a pre- coding (precoding) and the user scheduling (scheduling) In CSIT in , precoding and each user according to the number of data streams into a single data stream and multiple data streams in both cases . In each case , first examine the performance of different pre- coding algorithm, including two ZF, MMSE, SINR, SLNR. After they inspected the power allocation algorithm performance ( file name contains PD showed that it contained power allocation process ) . According to different indicators for power distribution , make a distinction in the file name , such as PD_CN representative channel norm-referenced index for power distribution . Scheduling section first observed the performance comparison RoundRobin, MaxH and MMSL)

基于MATLAB仿真的单载波频域均衡的源代码(MATLAB-based simulation of single-carrier frequency domain equalization of the source code)

说明：  可计算任意波形THD的小工具，非常方便；修改其输入波形即可得出结果(A tool for calculate THD)
