Abstract- In this paper, a hardware architecture for MIMOOFDM system synchronizer is presented.The proposed synchronization unit can achieve synchronization in the time-domain and frequency-domain. The time-domain synchronization can be achieved by a group of matched filters of ZCZ codes. Since MIMO-OFDM system have multiple transmitting antennas and multiple receiving antennas, every receiving antenna can receive the signal from all transmitting antennas. When the all sub-channels delay between receiving/transmitting antennas are different, every frame detection in receiving antennas will be interfered from other transmit
