Abstract
Abstract Orthogonal frequency division multiplexing (OFDM) has been most important mainstream technology considered for high data transmission speed. But, high peak to average power ratio (PAPR) diminishes system performance. Consequently, in this research work, pseudo random phase sequences based partial transmit sequence algorithm (PRS-PTS-Algo) has been considered. In order to obtain information back at receiver only index value of column of the phase sequences can be utilized. In addition, 8-PSK (phase shift keying) and 16-PSK modulation methods and diverse sub-carriers are considered. Simulation results clearly show that PRS-PTS-Algo provides remarkable reduction in the PAPR issue as compared with conventional OFDM system (Conv-OFDM) along with very efficient generation of phase sequences.
