Partial Transmit Sequence technique based on Particle Swarm Optimization for WOFDM PAPR reduction

This paper proposes Partial Transmit Sequence (PTS) technique for Wavelet Orthogonal Frequency Division Multiplexing (WOFDM) based on Particle Swarm Optimization (PSO) for optimum phase rotation factors searching and high Peak to Average Power Ratio (PAPR) reduction. PAPR performances of wavelet based OFDM adopting several wavelet families is compared to the conventional OFDM system. The system evaluation shows that the proposed PTS-WOFDM technique based PSO enhances the PAPR performances of conventional OFDM, PTS-WOFDM, PTS-OFDM and PSO based PTS-OFDM systems.
