PAPR Reduction of OFDM Signal by Novel – PTS Using Recursive Phase Correlation Factor with Low Computational Complexity

Orthogonal Frequency Division Multiplexing (OFDM) uses as a high speed information transmission technology with excellent anti-interference capabilities. High Peak-to-Average Power Ratio (PAPR) of transmitted signal is one of the major drawbacks in Orthogonal Frequency Division Multiplexing (OFDM) systems. To overcome the drawback of high PAPR of transmitted signal we propose the novel based partial transmitted sequence scheme in OFDM. Partial Transmit Sequence (PTS) is one of the most attractive schemes to reduce PAPR in OFDM systems. In the conventional partial transmitted sequence the computational complexity increases with number of sub blocks. To reduce PAPR we propose Recursive Phase Correlation Factor (RPCF) with low complexity. Performance analysis shows that the proposed scheme offers a better PAPR reduction when compare with the conventional-PTS scheme.
