说明：  这是SCMA和polar编码的matlab源文件(This file is the matlab source of the SCMA and polar coded)

说明：  GPS信号模拟软件，模拟GPS设备向串口输出0183格式标准语句，配合串口虚拟工具使用，可以在普通电脑上调试(GPS signal simulation software, which simulates GPS equipment to output 0183 standard statements to serial port, can be debugged on ordinary computer with serial virtual tools.)

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.)

说明：  使用pyqt编写的界面程序，实现串口网络通信(The interface program written by pyqt is used to realize the serial port network communication)

visual C++ MFC 环境下 串口的连接，收发数据的实现，串口探测工具部分功能的实现(Serial port connection)

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

文档中介绍首先介绍了多用户MIMO模型，以及LTE中的多用户MIMO方案，通过仿真分析总结出当用户数较少时，在高信噪比条件下，ZF方案的系统吞吐量性能明显优于PU2RC方案。(Document describes first introduced a model of a multi-user MIMO, and LTE multi-user MIMO scheme, by simulation analysis summed up when the number of users is small, at high SNR conditions, the system throughput performance of the ZF program superior PU2RC program.)

对移动通信中的多径多普勒频移进行详细的仿真，对学习这个的朋友有极大的帮助(Of mobile communication in multi-path Doppler frequency shift to conduct a detailed simulation study of the friends of great help)

多路复用写的一个可收发数据的串口应用程序(Write a multiplexer can send and receive serial data applications)

由中频信号捕获到跟踪、解算等一系列处理GPS接收机链路实现(Implementation of GPS receiver link)
