本程序是将串口实时接收到的数据，然后将数据进行曲线绘制。(The data received by serial port is plotted in real time.)

说明：  bpsk和4pam调制系统误码率和误符号率仿真，以及与理论值比较。(Simulation of BER and BER in 4pam modulation system)

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.)

D2D的自适应链路仿真，可根据信道状态，自选自调制方式(D2D adaptive link simulation, according to the channel state, optional self modulation)

说明：  matlab里使用simulink仿真出qpsk系统通过AWGN信道的调制解调过程，并分析其误码率(Using simulink in matlab to simulate the modulation and demodulation process of qpsk system through AWGN channel and analyze its bit error rate)

IEC103规约应用的知识要点文档，对学习iec103协议的人帮助很大(IEC103 application of the knowledge elements of the Statute of the document, to learn iec103 agreements were of great help to)

说明：  SMART ANTENNA BOOkS by lal chand

说明：  基于OQPSK，高斯信道和瑞利信道的matlab仿真程序(Matlab simulation program based on OQPSK)

实现时域与频域均衡MMSE方法的比较 采用64QAM调制(Comparison of the time domain and frequency domain equalization MMSE method)

说明：  qpsk信号插入导频，使用升余弦滤波器，利用导频估计信道，在simulink中仿真(inset pilot in QPSK signal, use square root raised cosine filters in simulink)
