A Novel OFDM Timing Synchronization Algorithm Based on Stochastic Approximation and ML Algorithm

Yanping Li and Liyong Zhang    

Abstract: ML algorithm has low computational complexity but its timing estimation is not good. In order to improve the problem, combination of stochastic approximation and ML algorithm is proposed. Using ML algorithm as timing coarse estimation and stochastic approximation algorithm as timing fine estimation, the simulation results show that the proposed algorithm can realize more accurate symbol timing than ML algorithm.
