Robust Timing Synchronization for OFDM Based Wireless LAN System
Overview In this paper, a robust and efficient frame detection and symbol timing synchronization technique suitable for IEEE 802.11a wireless LAN system is proposed. The proposed method does frame detection using a threshold comparison mechanism and performs Orthogonal Frequency Division Multiplexing (OFDM) symbol boundary detection using correlation techniques. This algorithm is a novel combination of self and cross correlation information to achieve symbol timing synchronization. The proposed algorithm can robustly detect the symbol boundary even under low SNRs, high frequency offset, and multipath.
