Reduction of PAPR in MIMO-OFDM/A System Using Polyphase Complementary Modulation

Balaji Naik.M , Ramana Reddy Gujjula,Bojja Durga Bhavani

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.
