Time synchronization algorithms for OFDM systems using the short and long training symbols are investigated in this paper. We only consider efficient low complexity schemes that are feasible for practical implementations. Different algorithms are compared in the context of IEEE 802.11Wireless Local Area Network (WLAN) systems. Based on the simulation results, some recommendations are made as to how the short and long training symbols can be effectively utilized for synchronization purposes
