说明：  载波同步是QPSK信号相干解调的一项关键技术。(Carrier synchronization signal coherent QPSK demodulation is a key technology.)

本源码是本人工作之余码的，CC2540低功耗蓝牙的notify工作方式总结，这源码是很好的理解notify例子，代码中有注释，希望对大家有所帮助(The source code is my spare time, notify work CC2540 Bluetooth low energy summary, this source is well understood notify example, the code notes, we hope to help)

Channel estimation for a MIMO-OFDM system for AWGN channel estimation technique Cyclic prefix length

在AWGN信号下，实现pi-4 QPSK调制解调(pi-4 QPSK modulation and demodulation)

激光传播模拟，模拟分布的光强、相位、时间信息(Laser propagation simulation)

Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置 串口属性的实例. 在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口 进行通信.串口通信方便易行,应用广泛. 一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是 半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点. 每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正 确的命令后作出应答. (Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)

大气波导下，电磁波射频追踪研究，利用Matlab进行仿真(Radio Frequency Tracking of Electromagnetic Waves in Atmospheric Waveguide)

本文系统的介绍了TQ2440开发板相关知识，对这方面的读者很有作用。(This article describes the system development board TQ2440 knowledge, useful in this respect the role of the reader.)

说明：  MFC编程 实现数据绘制成曲线。经兄弟推荐最终决定用两个控件MCSCOMM与TeeChart来完成此任务。MCSCOMM控件时vc自带的串口控件，TeeChart Pro是一个强大的VCL图表组件，支持上百种2D和3D图表风格，并提供40多个数学和统计函数、无限制的轴和22个调色板(MFC programming realizes data plotting into curves. After recommendation by brothers, we finally decided to use two controls, MCSCOMM and TeeChart, to accomplish this task. TeeChart Pro is a powerful VCL graphics component that supports hundreds of 2D and 3D graphics styles and provides more than 40 mathematical and statistical functions, unlimited axes and 22 palettes.)
