Abstract

This paper presents a effective iterative piecewise linear companding transform for PAPR reduction. It also presents an efficient iterative procedure of companding. This procedure mainly aims to mitigate the companding distortion that occurs during the clipping operation. This analysis provides a trade off between the reduction in PAPR and BER performance. Simulation results shows that proposed iterative piecewise companding transform (IPCT) can effectively reduce the PAPR.
