一篇带matlab源码的MIMO论文!对理解MIMO仿真很有意义

【实例简介】电力系统分析课程PPT

一个用saber仿真软件的buck电路双闭环仿真，可以直接运行，无需修改，模型采用电压电流双闭环，不是用电路搭建，用模型搭建，对学习saber控制系统建模很有帮助

这是用于目标跟踪的粒子滤波代码，用matlab编写的，很有借鉴性，一维情况下，非高斯非线性，其中将扩展卡尔曼滤波与粒子滤波进行比较，更好的说明了粒子滤波的优越性

Saber_H-2012.12 安装 说明 和 破解

实现BCH码的编译码，可自行设置（n,k,t），分别仿真了在AWGN 信道下qpsk/16qam等调制方式的误码率，采用MAP软解调。

详细内容，参见博客： Qt：QCamera打开系统摄像头，截图保存实例（http://blog.csdn.net/rl529014/article/details/53146253）

限幅(clipping)，是降低OFDM系统PAPR最直接的方法。根据峰均比的统计特性可知，高峰平比出现的概率极小，削去过高的瞬时高幅值,降低整个系统的误比特率性能，改善CCDF曲线

基于单片机智能灯光控制系统。内含c51源代码，原理图，元件清单

该系统是基于VC的MFC程序，程序里包括数据库备份文件，数据库是使用的SQL Server。实现的功能有：登陆功能，学生选课，管理员添加课程，删除，查看，教师评分功能！运行前要先把数据库文件还原，然后建立一个名为Student的数据源。数据库连接使用的是ODBC连接，该程序是基于单文档的MFC程序！！！

MOTIVATIONPropeller related acoustic signatures typically exhibit modulationcharacteristics. These modulation characteristics originate from the cavitationprocess that takes place in the water due to the cyclic movement of the propellerThe cavitation process is basically the collapse of air and vapor bubblesdue to variations in the static pressure. These variations in static pressure are aconsequence of the passage of the propeller blades through the water. Thismovement, cyclic in nature, causes amplitude modulation in the static pressureand as a consequence an amplitude-modulated(AM) signal can be detected in areceiverCyclostationary processing techniques have been used to detect andlentify analog and digital communication signals very successfully. Thesetechniques have the advantage of using a more realistic model for the signalthan the stationary model used in most of the more conventional signalprocessing techniquesB BACKGROUNDThe basic elements of cyclic spectral analysis are the time-variant cyclicperiodogram and the time-variant cyclic correlogram. These two functions form aFourier transform pair. This fact is known as the cyclic Wiener relation or thecyclic Wiener-Khinchin relation [Ref. 1: p. 49.1
