本程序实现了计算机图形学的一些重要算法（画直线，画圆，画椭圆，区域填充，图形裁剪，齿轮生成，三次样条曲线等等），源码和可执行程序均打包于文件中-this program is implemented some important algorithm of computer graphics such as drawing lines,drawing circles,drawing ellipse,area filling,Graphics clipping，gear wheel generati

通过对OFDM信号的CCDF曲线进行分析，得出了联合哈特莱变换和限幅算法降低OFDM信号峰均比的方法确实降低了OFDM信号的PAPR值-through the analysis of CCDF curve of OFDM signal, it is true to reduce the PAPR value of OFDM signal by use the method of the United Hart transform and clipping algorithm for PAPR r
