%X After introduction of MIMO_OFDM system mode and analysis of chaotic sequence produced by TD-ERCS map, proposed a new time and frequency synchronization algorithm based on chaotic sequence of MIMO_OFDM system. The algorithm utilized the excellent autocorrelation and cross correlation characters of TD-ERCS chaotic sequence, and fulfilled the precise estimation of the time delays and frequency offset of each sending antenna. The simulation results show that the new algorithm has a better synchronous precision and communication security.
