Peak Regrowth Reduction Based on Segmental Approach for OFDM/OQAM signals

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper proposes an Overlapped Segmental Deep Clipping (OS-DC) method to suppress the peak regrowth. OS-DC reduces Peak-to-Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing with Offset Quadrature Amplitude Modulation (OFDM/OQAM) signals without the need of multiple iterations. In OS-DC the clipping function is modified to deeply clip the high amplitude peaks and is applied to an OFDM/OQAM transmission system. This achieves up to four times reduction in peak regrowth in comparison to repeated iterative Overlapped Segmental Clipping and Filtering (OS-CF). Furthermore, it is also demonstrated that the proposed method improves signal quality compared to the normal clipping, for the same PAPR.
