基于DFT的MIMO-OFDM系统的信道估计算法研究代码
说明: MIMO系统仿真 MIMO技术可W极大地提升系统吞吐量和有效抵抗多径衰落的影响,被视作LTE的核也技术之一。信号检测模块又是MIMO系统中非常重要的一步,因为接收端收到的信号是经历了无线信道衰落影响的信号,与发送端发送的初始值之间差距较大,因此,在接收端首先应进行信道估计求出信道矩阵H,然后根据该信道矩阵的信息,从接收端还原出发送信号。因此,在MIMO系统中信号检测直接彰响着系统系能的提升。本章将先介绍高移动性MIMO无线信道的建模方法(simulation of MIMO-OFDM communication system)

:介绍了一种基于数字信号处理器(DSP)的移相调频(Phase-Shifted and Frequency-Varied,PSFV)PWM控制
逆变电源,给出了主电路拓扑结构,分析了其控制原理并设计了其控制程序流程图。新颖的PSFV 控制能够实现输出
电压90%的调整率,输出电流波动小于单纯移相调功PWM方式,并在轻载时保持连续。功率开关器件零电压零电流
通断(Zero-Voltage-Zero-Current Switching,ZVZCS)软开关的实现,有利于进一步提高开关频率和降低开关损耗。采用
高性能的专用DSP 芯片TMS320F2812 实现了系统的数字控制,满足了系统控制的灵活性和实时性,减小了系统的
体积和生产成本。仿真分析和实验结果证明了此控制模式的可行性与合理性。()

NetRecorderDOC
网络录音盒系列资料之一:网络录音盒实现文档。本文档系本人毕业设计的论文部分,详细的介绍了一种嵌入式网络录音盒的设计与实现。所谓网络录音盒是指一种可以通过网络向远程的计算机提供录音盒所在位置的监听以及录音功能的网络设备。本人已经上传了录音盒相关的所有资料,为了方便用户选择自己所需的内容,本人将所有资料分为三部分上传:1、文档;2、源码;3、测试过程。(network data recording boxes series one : Network box on document recording. This document is designed my graduation thesis, a detailed introduction of a sound recording box Embedded Network Design and Implementation. The so-called network recording box refers to a network through a remote computer to the provision of recording the location of the box and recording wiretapping functional network equipment. I have uploaded the recording box all the related information, in order to facilitate the user to choose the content they need, I will be all the information is divided into three parts Upload : 1, the document; 2, the source; 3, the testing process.)
