Abstract

The progression in technology
requires improved modulation techniques for wideband digital communication
systems. Orthogonal frequency division multiplexing is efficacious systems to
fulfill high-speed data transmissions needs. However, high peak-to-average
power ratio (PAPR) is one of the significant limitations on the performance and
power efficiency of OFDM systems. Due to industrial and scientific relevance,
the assessment of the PAPR reduction has become popular subject in the current
decade. This study presents the combination of bat algorithm with partial
transmit sequence scheme as an efficient PAPR reduction method with an
alleviated computational load. A set of simulations with different partial
transmit sequence schemes are performed to comparatively evaluate the PAPR
reduction performance of the partial transmit sequence based on bat algorithm
scheme in OFDM system. The simulation results elucidate that BA-PTS scheme can
provides better PAPR reduction performance with less computational load.
