PAPR抑制主要有SLM,PTS以及限幅法，主要对限幅法进行仿真，对比不同限幅阈值的限幅效果(PAPR suppression mainly includes SLM, PTS and amplitude limiting method. It mainly simulates the amplitude limiting method and compares the amplitude limiting effect of different amplitude limiting threshold.)

串口程序，用于通过串口控制空调，可以在这个程序基础上修改其他代码(used for serial port)

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)
