PAPR reduction of post-OFDM waveforms contenders for 5G & Beyond using SLM and TR algorithms

This paper investigates the performances of signal processing based PAPR reduction methods to increase the efficiency of power amplifiers to be used in 5G and B-5G context along with multi-carrier modulations. The considered waveforms in this work are Weighted Overlap and Add-OFDM (WOLA-OFDM), Universal Filtered MultiCarrier (UFMC) and filtered-OFDM (f-OFDM), by taking conventional CP-OFDM as reference. The PAPR reduction methods used are Selected Mapping and Tone Reservation and their complexity is evaluated in terms of number of complex multiplications.
