Robust Timing Synchronization Preamble for MIMO-OFDM Systems Using Mapped CAZAC Sequences

Abstract

International audienceThe paper proposes a time and frequency synchronizaton algorithm for MIMO-OFDM systems.This algorithm designed a training sequence that based on CAZAC sequence,it has sleep timing measuring function waveform,it shows satisfactory performance of delay estimation of each antenna.Simulation results indicate that this timing synchronization algorithm shows satisfactory performance in Rayleigh and AWGN channel at a low signal-to-noise ratios(SNR)
