A Quick Convergence Active Constellation Extension Projection onto Convex Sets Algorithm for Reducing the PAPR of OFDM System

High Peak to Average Power Ratio, commonly abbreviated as PAPR, represents the main concern in the implementations of all multicarrier modulation schemes such as Orthogonal Frequency Division Multiplexing. Many PAPR reduction techniques were proposed to solve this problem. Amongst these schemes is the Active Constellation Extension (ACE) which is recognized as a promising method that provides higher gains with neither Bit Error Rate (BER) degradation nor receiver side information transmission. In this investigation, we focus on this scheme in its Projection onto Convex Sets (POCS) variant. We propose a quick POCS-ACE convergence scheme that achieves good performances from the first iteration without degradation in BER.
