Robust Symbol Timing Synchronization for OFDM Systems Using PN Sequence

A. M. Khan, Varun Jeoti, M. A. Zakariya, and M. Z. Ur Rehman
Abstract— This paper presents the symbol timing synchronization for OFDM receivers using PN sequence of values 1 or -1. The proposed design preamble is based on the correlation property of Pseudo Noise (PN) codes. Simulation results show that the proposed scheme is more robust to multipath fading channel than the conventional PN-based Park method, particularly at low SNR. It helps in setting the high threshold value in timing metric estimator.

Index Terms— Orthogonal frequency division multiplexing (ofdm), pn (pseudo noise), symbol timing offsets (sto) and preamble.
