OFDM is known as one of the most favorable modulation techniques for communication over frequency selective wireless channels, and is widely used in telecommunication standards. But a major problem with OFDM is its high Peak to Average Power Ratio (PAPR), which decreases the efficiency of the power amplifier. New peak-toaverage power ratio (PAPR) reduction approach for MIMO-OFDM/A is developed based on the well known Complementary Code Modulation, is one of the techniques to reduce the PAPR of the OFDM signal.
