上位机与三菱PLC之间进行TCP/IP通讯(communication between PC and PLC)

可以实现无线通信，代码简单便于理解，是基于wince平台的(Wireless communications can be achieved, the code simple and easy to understand, is based on the wince platform)

用VC++6.0编写的USB通讯测试的程序，可以实现查找PC的USB外设，读取USB外设的设备描述符等功能。对USB通讯初学者有很大的帮助。(Written in VC++6.0 using USB communications test procedure, can be achieved to find PC' s USB peripherals, read the USB peripheral device descriptor functions. USB communication to the very helpful for beginners. )

说明：  ns2.33这是目前比较新的ns2版本，欢迎下载(ns2.33 This is relatively new ns2 version, welcome to download)

这个是华为的VoIP文档，讲述清晰，值得阅读！(This is Huawei' s VoIP documents, about clarity, it is worth reading!)

根据手机双麦克风进行定位 ，电脑客户端程序，c++源程序(According to the mobile phone microphone to locate )

实现串口通信 可以收发数据 可以是数字也可以是ASCII(Serial communication)

一个与仪表通讯的上位机程序源码，采采用RS232通讯，协议为MODBUS (A host computer program source code with the instrument of communication, mining RS232 communication protocol MODBUS)

本论文以OFDM系统为基础，介绍了OFDM系统的基本原理，以及使用OFDM技术的优势所在，并且展望了今后的无线移动技术的发展前景。在简单介绍OFDM原理的同时，着重阐述了OFDM系统在不同信道环境和不不同实现方式下的误码性能。主要包括了OFDM系统在加性白高斯信道，在加性白高斯信道和多径干扰两种不同信道环境下系统的误码性能，其中后者还研究了系统在有保护间隔与无保护间隔的误码性能比较。在理论分析的基础 (This thesis is based on the OFDM system, the basic principle of the OFDM system, as well as the advantages of using OFDM technology, and future prospects for the development of future wireless and mobile technologies. OFDM principle in brief, focusing on the BER performance of OFDM systems under different channel conditions and different implementations. Including OFDM system in additive white Gaussian channel, additive white Gaussian channel and multipath interference of two different channel environment, the system BER performance, the latter of which also studied the system in a protected interval without guard interval BER performance comparison. The basis of theoretical analysis)
