OFDM中降低峰均比的方法，将传统的SLM法，改进的SLM法和限幅加改进SLM法进行比较(Compare OFDM PAPR reducing methods in the traditional SLM method, improved SLM method and limiter plus improved SLM method)

QT编写的CAN通讯源代码文件，通讯盒子用的是珠海芯创的can盒(The source code file of CAN communication written by QT. The communication box is the can box of Zhuhai Xinchuang.)

说明：  在n个城市建设通信网络，只需架设n-1条线路即可至少包含10个城市，城市数n由键盘录入，城市坐标由随机函数产生小于100的整数(In the construction of communication network in n cities, only n-1 lines are needed to include at least 10 cities. The number of cities n is input by keyboard, and the coordinates of cities are generated by random functions into integers less than 100.)
