Design New Companding Scheme to Reduced PAPR for FBMC/OQAM in 5G Communication

In last few years, there is an increased requirement in the demand for high data rates over the wireless communication system. This demand motivated the researchers worldwide to move to higher generations of wireless communication systems characterized by high data rate, low drive motivation clamor, and high information move limit efficiency transmission. Therefore, Filter Bank Multicarrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM) might be outstanding amongst other waveform utilized in the up and coming age of remote correspondence. But it is undergoing from a high peak to average power ratio. In this paper, we propose a new scheme called Weibull a nonlinear companding “WC” to reduce PAPR in the FBMC. This scheme is based on the transform of the originally Gaussian distributed FBMC signal magnitude into Weibull Distribution to effectively reduce the PAPR while preserving the BER performance. The reproduction results show that the proposed WC conspire viably lessen the PAPR by decreasing the pinnacle flags and developing the little signals, adequate BER execution.
