Design and Comparison of GFDM Receivers for 5G Communication Systems

Abstract

In the forthcoming communication systems, new technologies arise including machine type communication (MTC), tactile internet and wireless regional area network (WRAN), internet of things (IoT) etc. Due to numerous advantages, generalized frequency division multiplexing (GFDM) which can bring lower out of band emission (OOB), lower peak to average power ratio (PAPR) and lower latency if compared to orthogonal frequency division multiplexing (OFDM), is an important candidate for SG communication systems. In this paper, by considering Meyer RRC filter (pulse shaping filter) which is used for GFDM waveform in the transmitter side, receiver structures compared such as zero forcing filter (ZF), matched filter (MF) and minimum mean square error filter (MMSE) in terms of their computational complexity, symbol error rate (SER) and self-generated interference (ISI, ICI).
