PAPR reduction in FBMC/OQAM systems using active constellation extension and tone reservation approaches

Filter Bank based Multicarrier communication with Offset Quadrature Amplitude Modulation (FBMC/OQAM) has been gaining considerable interest as an important competitor to Orthogonal Frequency Division Multiplexing system (OFDM). However, FBMC/OQAM signal inherits the same drawback of High Peak to Average Power Ratio as OFDM signal. Because of the overlapping structure of FBMC/OQAM symbols, the direct application of the conventional PAPR reduction scheme originally proposed for OFDM is not effective. In this paper, we investigate the performance of Smart Gradient Project Active Constellation Extension (ACE-SGP) and Tone Reservation (TR) approaches in PAPR reduction for FBMC/OQAM signals. Indeed, we introduce three PAPR reduction schemes for FBMC/OQAM system based on ACE-SGP, TR and a hybrid one. The performance of the three schemes are presented and compared with those of the OFDM system.
