Performance of GFDM and OFDM over Fading Channels

Abstract

Flexibility feature is the main feature for generalized frequency division multiplexing (GFDM); digital transceiver can using any pulse shaping filter. While it was limited by rectangular pulse shape in Orthogonal frequency division multiplexing (OFDM). In this work Rayleigh and Nakagami- fading channel are depended with different Nakagami fading parameter, furthermore Additive White Gaussian noise (AWGN) to describe the GFDM performance in terms of symbol error rate. Also make performance comparison between the two multicarrier physical layer modulations OFDM and the new GFDM over above channels by simulation and theoretical expression.
