Abstract :
This paper presents the synchronization preamble deign with ZCZ (zero correlation zone) codes, for MIMO-OFDM system which has Q transmit and P receiver antennas. Because the ZCZ codes have good properties that autocorrelation is unit pulse and cross-correlation is zeros, the design for MIMO-OFDM synchronization preamble is solution to the co-channel interference in the different antennas. Furthermore, the frame preamble can be distinguished in the low SNR at receiver of MIMO-OFDM system.
