Abstract

A peak-to-average power ratio (PAPR) reduction scheme with low complexity is proposed for the multicarrier spread spectrum (MC-SS) system in personal area network (PAN). Traditional clipping and filtering scheme requires a high oversampling rate to meet the emission mask requirements. This would cause high power consumption for mobile PAN devices in personal network. To solve the problem, upsampling is introduced between clipping and filtering in this paper to reduce the oversampling rate. A simplified implementation structure is also derived for the proposed scheme. Simulation results show that its complexity is about 65% of the conventional scheme while achieving satisfying performance.
