自己编写的ofdm系统中MInn算法，可以实现精确的符号定时同步-I have written SCH algorithm in OFDM systems, to achieve timing synchronization and frequency offset estimation

对不同信噪比下的minn符号同步仿真，可在其上对其他符号同步算法进行改动。(Simulation of Minn symbol synchronization under different SNR can change other symbol synchronization algorithms on it.)
