Abstract
Peak to average power ratio (PAPR) is a major problem that affects the performance of multicarrier systems. Filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is one of modulation schemes that has raised the attention of researchers given its superiority in terms of spectral efficiency. As any other multicarrier modulation system, FBMC/OQAM also suffers from high PAPR. Borrowing from the fact that the conventional PAPR reduction techniques such as partial transmit sequence (PTS) and discrete Fourier transform (DFT) spreading does not work well in FBMC/OQAM systems because of the overlapping structure of the symbols, in this paper, we investigate the effects of these methods on FBMC/OQAM systems and compare the results with other existing reduction techniques.
