AMmct-A new algorithm for joint channel and carrier frequenq-offset (CFO) estimation in MIMO-OFDM using a training sequence is proposed. This algorithm is developed based on a maximum likelihood (ML) criterion, and jointly estimates the CFOmd all frequeneyselrctive channel parsmeterr in time domain. To evdush the performance of the algorithm, the Cramer-ko Bound (CRB) for the problem is calculated Computer simulations show that the proposed algorithm c m meet the CRB in certain Signal-Noise
