ASK4

加窗QPSK-OFDM调制解调，每个OFDM符号采用QPSK调制方式，并画出了时域对比图(Windowed QPSK-OFDM modulation and demodulation, each OFDM symbol using QPSK modulation and a time-domain comparison chart shown)

提供实现了（2，1，7）卷积码的维特比译码的源程序，采用了最大似然算法，介绍了软判决维特比译码算法过程的三个步骤：初始化、度量更新和回溯译码。(for achieving a (2,1,7) Convolutional Codes Viterbi decoding of the source, using the maximum- likelihood algorithm, introduced a soft-decision Viterbi decoding algorithm of the three steps : initialization, Metric update and backtracking decoding.)

说明：  sip开发相关资料集,为sip开发人员提供了很丰富的资料,适合初学者.

fpga时钟，是入门的基础；希望对大家有帮助！(fpga clock, is the entry of the base want to help you!)

本OPC Client程序基于OPC DA 2.0开发制作。其操作方式和功能均按照OPC的测试工具OPC client模仿编写。(The program is based on OPC Client OPC DA 2.0 development and production. Its mode of operation and functional test tools in accordance with OPC OPC client imitate write.)

OPNET14.5的帮助文档，几乎所有的现行阶段的教材都是由该软件帮助文档改编或缩减而成，所以该文档为OPNET学习者必备手册之一。(OPNET14.5 the help of documents, almost all of the current phase of the teaching materials are adapted to the software help files or reduced form, so the document must have the manual for one of OPNET learners.)

说明：  GPS串口通信程序，新建了一个数据库ACCESS，在显示当前GPS信息的同时可以存储以前记录过的信息，保存在数据库中，便于以后查阅。当前GPS信息包括：时间，经度，纬度，速度，真实航向以及磁偏移(GPS serial port communication program, a database of new ACCESS, show the current GPS information can be stored at the same time the information previously recorded, stored in a database for easy access later. The current GPS information including: time, longitude, latitude, speed, true course and magnetic offset)

说明：  MATLAB仿真，对比OFDM与F-OFDM性能(Compare F-OFDM with OFDM using MATLAB)

用OPNET实现802.11MAC协议DCF协议(use OPNET to develop 802.11MAC )

说明：  实现各种MIMO检测算法，包括MRC，ZF，MMSE和SIC(Implementation of MIMO Detection Algorithms)
