Timing and Frequency Synchronization For Distributed MIMO-OFDM Systems

摘要

This paper proposes a time and frequency synchronization 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 and the carrier frequency. Simulation results indicate that this timing synchronization algorithm shows satisfactory performance in rayleigh channel and A WGN channel at a low signal-to-noise ratios(SNR).
