Abstract: The combination of multiple-input multiple-output (MIMO) transmission with orthogonal frequency division multiplexing (OFDM) technique is deemed as the candidate to the upcoming fourth generation (4G) wireless communication systems. This thesis addresses several initialization issues for MIMO OFDM systems. We answer the following questions: how to use a few pilot carriers to track the timing offset (TO) and the carrier frequency offset (CFO), how to apply the blind channel estimation when the number of the transmit antennas is greater than or equal to the number of the receive antennas, how can we make the blind channel estimation more robust to parameter uncertainty. All these questions are interesting yet never answered or partly answered through the existing literatures.
