STUDY ON PAPR REDUCTION PERFORMANCE OF IPTS FOR FBMC SIGNALS IN THE NON-LINEAR CHANNEL.
The Filter Bank Multi-carrier (FBMC) modulation with one of its variants Offset Quadrature Amplitude (OQAM) has increased considerably in the field of research for the next generation of future broadband wireless communication systems. However, one of the drawbacks of the FMBC signals is the Peak to Average Power Ratio (PAPR). To improved PAPR value, Partial Transmit Sequence (PTS) method can improve PAPR as increasing the number of predetermined discrete phase factors and the number of clusters. We study the Improved Partial Transmit Sequence (IPTS) method, which can reduce the PAPR for a multicarrier modulation signal. In OQAM based FBMC (OQAM-FBMC) under the non-linear channel. In this paper, we investigate a PAPR method to reduce the PAPR and the computation complexity by using the IPTS method when applying to the OQAM-FBMC system. The results reveal that the IPTS in the performance of PAPR reduction and Bit Error Rate (BER) of the study scheme verified by using various computer simulations.
