PAPR Analysis of MB-OFDM UWB Signal using Hybrid PS-GW optimized PTS Technique

Multiband Orthogonal Frequency Division multiplexing Ultra-Wideband (MB-OFDM UWB) is famous and striking stratagem used in wireless communication for massive broadcast of data with greater rate was approach is used. However, like OFDM, major problem identified in MB-OFDM UWB system is high PAPR. “Partial Transmit Sequences” (PTS) is acquainted approaches to decrease PAPR in OFDM since this doesn’t give distortion in the signal. A hybrid optimization algorithm called PS-GW is used along with PTS to lessen PAPR for MB-OFDM UWB is considered in this article. A best mixture of phase turning factors is attained from PS-GW algorithm. PS-GW is a hybrid of “Particle Swarm Optimization (PSO)” and “Grey Wolf Optimization (GWO)”. The results of this proposed method show that PAPR was reduced, and computing complexity was effectively reduced.

I. Introduction

The technology for short range is UWB sends signals at extremely high data rates across small distances. [1]. “An OFDM-based UWB system is created and integrated with a multi-banding technique for efficient utilization of accessible UWB spectrum [2], [3]”.
