OFDM
利用MATLAB软件对OFDM系统做出仿真。仿真中采用QPSK调制技术，并加入高斯白噪声，最终得到QPSK星座映射图以及BER曲线图。由仿真结果可以看出，OFDM在高斯信道具有良好的抗噪声性能，误码率较低。(MATLAB software is used to simulate the OFDM system. In the simulation, QPSK modulation technology is used, and Gauss white noise is added, and the map of the QPSK constellation and the BER curve are finally obtained. It can be seen from the simulation results that OFDM has good anti noise performance and low error rate in Gauss channel.)

ModbusPollCS
某智能设备公司开关量采集系统（Modbus RTU），很不错哦！对于该类设备基本上都可以通用，只是“寄存器地址”不一样。我就参照该源程序写了一款SOS应急呼叫系统、酒店客房插卡取电、退房呼叫系统等。保证原创，独一无二。(A smart device switch acquisition system (Modbus RTU), very good, oh! Can be generic, such equipment is basically just not the same register address. I refer to the source Admission card, write a SOS emergency call system, hotel rooms, check out the call system. Guaranteed original, unique.)
