PAPR Evaluation in Multi-Mode SDR Transceivers

Abstract

This paper presents a study of the impact of peak-to-average power ratio in multi-mode software defined radio transceivers. The nonlinear distortion degradation will also be studied both at the SDR transmitter and receiver. Moreover the use of crest factor reduction schemes based on clipping is presented, by showing that clipping followed by filtering should be used carefully in order not to degrade the overall performance.
