dc.description.abstractFilter Bank Multicarrier(FBMC) is a strong waveform contender for 5G communication because of it’s very low out of band radiation and high spectral efficiency. Like OFDM, FBMC also suffers from high peak to average power ratio(PAPR) problem which reduces power amplifier efficiency. Here we used FBMC-OQAM(offset quadrature amplitude modulation) which is the most efficient method among all FBMC schemes. Thereare several PAPR reduction techniques. Tone Injection(TI) is one of the PAPR reduction technique in which we add equivalent constellation points to the original constellation point in such a way that PAPR will reduce without compromising spectral efficiency. Companding is another PAPR reduction technique in which compression of low amplitude signal and expansion of large amplitude signal in the transmitter side and reverse operation in the receiver side is performed to reduce the PAPR of signal.In this paper, we proposed a PAPR reduction scheme based on the combination of tone injection and companding techniques. The simulation results show that the combined method gives better result compared to TI and Companding methods taken separately.en_US
