Modeling Simulation and Performance Analysis of PAPR in FBMC 5G System
Pooja Chaudhary,  Dr. Ashok Sirohi
Recently, filter bank multi-carrier (FBMC) has appeared great interest as an alternative to orthogonal frequencies Division Multiplexing (OFDM). FBMC plan has increased Frequency efficiency and low out of band (OOB) emissions Compared to OFDM. However, FBMC still encounters high positions Peak-to-average power ratio (PAPR) in OFDM systems. Some OFDM-based PAPR reduction technology has been adopted FBMC system. In this paper, new technologies for PAPR reduction The proposed FBMC system is based on its evolution Use phase rearrangement (PR) and modified PR (MPR) techniques Used in OFDM systems. Different from SC-FDMA (single carrier frequency division) Multiple access), just combine DFT (Discrete Fourier Transform) Spread spectrum and FBMC-OQAM (filter bank multi-carrier With offset quadrature amplitude modulation) only leads to The marginal PAPR (peak average power ratio) is reduced. Using the single carrier effect of DFT propagation, special The condition of the IQ coefficient of each subcarrier (in phase Should be satisfied with the quadrature phase channel. In order to further increase the quantity reduced PAPR, we generate DFT extension and ITSM condition in FBMC waveform and select the one with the lowest peak power. Even if there are multiple Candidate generation, the main calculation part such as DFT Share with IDFT, just execute once, unlike traditional SI (side information) based PAPR reduction Program.
