实现20m双绞线有线通讯，一端控制另一端小灯亮暗，反过来，一端发送字符，另一端显示浮点数(Realize 20m twisted-pair cable communication, one end controls the light of the other end, conversely, one end sends characters, the other end shows floating-point numbers.)

该工程是有关CPFSK（连续相位调制）的完整工程。帧结构包含训练序列、前导码、同步码、数据长度等信息，使用正交调制方式产生CPFSK的信号，生成基带IQ数据。接收端包含帧同步、滤波、解算长度等算法。可实现任意长度字符串的无线发送与接收。工程十分完整喝强大，可直接用于各大SDR平台的验证。(The project is a complete project of CPFSK (continuous phase modulation). The frame structure contains training sequence, preamble, synchronization code, data length and other information, and uses orthogonal modulation to generate CPFSK signals and generate baseband IQ data. The receiver includes algorithms such as frame synchronization, filtering, and calculating length. It can realize wireless sending and receiving strings of arbitrary length. The project is complete and powerful, and can be directly applied to the verification of major SDR platforms.)

LDPC码不同译码算法对比。码长512，码率1/2.(LDPC code decoding algorithm comparison. Code length of 512, a rate 1/2.)

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(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.)

IEC60870-5-103通信规约的从站模拟软件，可以模拟一个采用单片机驱动的继电保护设备，自动向主站程序上送数据并响应主站数据的数据问询请求，并有可选择的状态变位和扰动数据进行上送(IEC60870-5-103 communication protocol slave simulation software can simulate a single-chip computer-driven protection equipment, automatic procedures to send data to the master station and respond to data inquiries master data requests, and there is an optional state displacement and disturbance data sent)
