Combination of multiple-input multiple-output (MIMO) with orthogonal frequency division multiplexing (OFDM) has became a promising candidate for high performance wireless communications. Nevertheless one major disadvantage of MIMO-OFDM systems lies in a prohibitively large peak-to-average power ratio (PAPR) of the transmitted signal on each antenna. In this thesis we extend from SISO to MIMO systems a method based on allocating dedicated subcarriers for PAPR mitigation. These subcarriers are located instead of unused subcarriers of OFDM spectrum under the assumption they all fall under the mask. This is originally cleared up with a SOCP optimization algorithm applied before space time coding scheme. This jointly mitigates PAPR on each MIMO ...
