A smart tone reservation scheme for reducing the high PAPR of the FBMC/OQAM signal

Abstract

High Peak to Average Power Ratio (PAPR) of the Filter bank Multi-carriers Modulations (FBMC) signal has been extensively addressed in recent research studies. In this paper, we suggest an optimized and novel version of the overlapped Sliding Window Tone Reservation (SW-TR) algorithm in order to reduce the PAPR of the FBMC/OQAM signal. Our PAPR reduction scheme termed Smart Tone Reservation (STR) uses the Smart Gradient Project (SGP) algorithm to accelerate the convergence rate of the SW-TR algorithm. Simulation results indicate that the suggested PAPR reduction scheme for FBMC/OQAM is not only efficient in reducing the PAPR of the FBMC/OQAM signal with only one iteration but also outperforms OFDM with SGP-TR scheme.
