Abstract
Generalized Frequency Division Multiplexing GFDM is one of the multicarrier modulation techniques used in 5G that was derived from Orthogonal Frequency Division Multiplexing (OFDM). The main feature of GFDM is a pulse shaping the transmitted symbol to enhance the power spectral density of the transmitted signal and decrease the out-of-band (OOB) radiations, which will increase the spectral efficiency of the transmitted signal. In this paper, the Gaussian pulse shaping filter was introduced to shape the transmitted symbols of a simulated GFDM system. A comparison with the conventional shaping functions was also made to evaluate the Gaussian pulse shaping filter results. The simulated results show that the spectral efficiency was improved by (14.2) dB without effect on the overall system performance.

Keywords
