Outage performance analysis of pulse-shaped multicarrier waveform for 5G in frequency-selective fading environments

Abstract

This paper presents the outage performance of fifth generation (5G) candidate waveform, Generalized Frequency Division Multiplexing (GFDM), in LTE-A based frequency-selective channels (FSCs). With the advent of new standards for PHY layer modulation for 5G mobile communication systems, several advanced waveforms have been proposed to surpass Orthogonal Frequency Division Multiplexing (OFDM). GFDM shows great promise for applications in opportunistic cognitive radio in highly fragmented spectrum because of its flexible filtered multi-carrier structure and ultra-low out-of-band (OOB) leakage. The outage performance of GFDM system is considered for high user density scenarios at low-load and full-load conditions with un-coded transmission in LTE-A channel models and compared to OFDM. Analysis of simulation results suggests that GFDM achieves improved outage performance than OFDM, irrespective of system load, especially for Pedestrian-A channel. This novel perspective to looking at performance of GFDM provides a new dimension to its scope in TV white space based intelligent radio receivers.
