  • Abstract:
    Generalized frequency division multiplexing (GFDM) is a new candidate technique for the wireless fifth generation (5G) standard based on multi-branch multi-carrier filter bank. Unlike OFDM, it enables the frequency and time domain multi-user scheduling and can be implemented digital. It is the generalization of traditional OFDM with several added advantages like the low PAPR (Peak to Average Power Ratio). Taking advantage of the high degree of flexibility in frequency band selection, GFDM apparently seems more suitable for the bandwidth limited UWA systems. The multi carrier scheme has both the advantage of making full use of the fragment spectrum and the merit of low PAPR, which will reduce the power consumption and save the hardware cost. Therefore, the influence of the pulse shaping filter on PAPR performance of the GFDM system and the comparison of PAPR in OFDM and GFDM will be demonstrated in this paper.
