Orthogonal frequency division multiplexing is efficacious systems tofulfill high-speed data transmissions needs. However, high peak-to-averagepower ratio (PAPR) is one of the significant limitations on the performance andpower efficiency of OFDM systems. Due to industrial and scientific relevance,the assessment of the PAPR reduction has become popular subject in the currentdecade. This study presents the combination of bat algorithm with partialtransmit sequence scheme as an efficient PAPR reduction method with analleviated computational load. A set of simulations with different partialtransmit sequence schemes are performed to comparatively evaluate the PAPRreduction performance of the partial transmit sequence based on bat algorithmscheme in OFDM system. The simulation results elucidate that BA-PTS scheme canprovides better PAPR reduction performance with less computational load. KW - Bat Algorithm KW - OFDM KW - PAPR KW - PTS CR - 1.
