This thesis presents the scheme of CFO estimation in the MIMO-OFDM systems with the minimum error probability based precoder for reducing PAPR. First, a minimum error probability based precoding matrix to reduce the PAPR of OFDM signals is designed. The CFO estimation is based on maximum likelihood (ML) solution. Simulation results show that the mean square error (MSE) performance of CFO estimator in multiple antennas OFDM systems is better than that with the single antenna OFDM system.
