Abstract

Computational complexity considers as challenging issue in conventional Partial Transmit Sequence (PTS) scheme, even though it has good performance to reduce PAPR. In this paper, one of the recently developed bio-inspired algorithm named Chicken Swarm Optimization (CSO) is implemented with the combination of Partial Transmit Sequences to reduce PAPR, one of the most featured problems in OFDM system. Results show that CSO with PTS scheme reduces the computational complexity and improves the reduction of PAPR up to 2.25 dB at 0.0011 complementary cumulative distribution function (CCDF) for an unmodified OFDM signal.
