BER analysis of PAPR reduction techniques in SFBC OFDM system: A review

Abstract

The OFDM gives high data rate but it has disadvantage of high Bit Error Rate and high Peak-to average power ratio (PAPR). Space frequency block coded OFDM system (SFBC-OFDM) has overcome drawback of high BER because of its full transmission diversity with higher capacity. But large Peak to average Power ratio (PAPR) of OFDM and SFBC OFDM system is amplify signal non linearly and it degrade performance of system in terms of bit error rate(BER). There are different PAPR reduction techniques available to overcome large PAPR But these PAPR reduction technique reduce PAPR by paying cost bit error rate. Proposed paper gives comparative study of different PAPR scrambling technique with respect to BER calculation.
