Generalized Frequency Division Multiplexing (GFDM) has been proposed as a potential modulation candidate for 5G communication systems. Unlike the current Orthogonal Frequency Division Multiplexing (OFDM), GFDM has the flexibility to cover various types of waveforms. However, GFDM inherits the peak-to-average power ratio (PAPR) problem from the OFDM system. The high PAPR of the GFDM transmitted signal introduces non-linearity which may lead to power inefficiency in the high power amplifier (HPA). This is a crucial issue for low power devices. This paper proposes a design of the pulse shaping filter using computationally efficient optimisation method to reduce the PAPR of the GFDM system. The numerical results illustrate the effectiveness of the proposed method in reducing the PAPR of the GFDM transmitted signal.
