中文说明：IEEE802.16是一种广泛使用通信协议，其物理层采用OFDM调制方式，进行物理层解调的第一步就是进行定时同步处理，本程序完整实现了OFDM定时同步的全过程，绘制了相应的波形。
English Description：
IEEE802.16 is a widely used communication protocol. Its physical layer adopts OFDM modulation mode. The first step of physical layer demodulation is timing synchronization. This program completely realizes the whole process of OFDM timing synchronization and draws the corresponding waveform.
