摘　　要：针对OFDM系统符号定时,采用了两种经典算法的结合——符号同步两步算法,提出符号同步低复杂度算法,并进行分析与仿真,结合频率偏移估计比较两种算法性能。仿真结果表明,该方案中的低复杂度算法的符号定时精度较高,且算法简单。A two - step algorithm combining with two classical algorithms is adopted, and an optimum algorithm with low complexity is presented for symbol, synchronization of OFDM systems. The algorithm is analyzed, simulated and compared combined with frequency -offset estimation. The simulation results show that the low -complexity symbol synchronization is not only precise but also simple.
