Performance Enhancement of OFDM System Using Modified PTS (MOPTS) PAPR Reduction Algorithm

Abstract

This research paper depicts a modified partial transmitted sequence (MOPTS) algorithm by applying the normalized Riemann matrix (C) rows for phase sequences with discrete cosine transform (DCT) in time domain for diminishing the peak to average power ratio (PAPR) of several modulations under many sub-carriers based orthogonal frequency division multiplexing (OFDM) after distributing the information into numerous blocks and optimizing with the assistance of phase sequences. Since, original PTS (ORIPTS) algorithm makes use of phase sequences which are random and designing of those phases are also tedious. Henceforth, in this research manuscript we are suggesting a MOPTS algorithm which has definite phase sequences of normalized Riemann matrix (C) along with DCT. Simulation outcomes clearly indicate the noteworthy PAPR performance of MOPTS in comparison with PAPR of original OFDM (OFDMORIPAPR) and ORIPTS.
