Abstract

The Nonlinear Companding Transform (NCT) distortion technique is proposed for reducing the high Peak –To –Average Power Ratio. This proposed scheme reduces the PAPR by compressing the peak signals and expanding the small signal while maintaining average power constant selecting transform parameters. Finally simulation results show that the proposed technique outperforms compared to Repeated Clipping and Filtering (RCF) technique in terms of low clipping ratio problem, peak re-growth, out-of-band interference (OBI), PAPR reduction and BER Performance.
