Generalized frequency division multiplexing (GFDM)” is a new waveform modulation technique for next-generation wireless communication systems. However, it also has the drawback of a high peak-to-average power ratio (PAPR) like Orthogonal Frequency Division Multiplexing (OFDM). In the work, a simple clipping and filtering technique is proposed for PAPR reduction of the GFDM signal and the performance of the GFDM system with a polynomial model of HPA is shown for different performance metrics. The simulations are performed with a memoryless polynomial model of HPA. The BER performance of the proposed scheme is compared with orthogonal frequency division multiplexing (OFDM), which is a popular modulation scheme for 4th Generation wireless communication systems. It is clear from the results that PAPR and out-of-band leakage in the GFDM signal is reduced up to a large extent after applying the clipping and filtering method as compared to the OFDM signal maintaining almost equal BER performance.
