GFDM-Based Cooperative Relaying Networks with Wireless Energy Harvesting

In this paper, the concept of wireless power transfer and wireless information transmission, which have recently received special attention for improving energy efficiency in wireless communication systems, are investigated. In particular, we focus on a cooperative communication network consisting of a source node, an energy-constrained relay node and a destination node. In contrast to conventional wireless-powered cooperative networks, a GFDM waveform-which is an emerging candidate waveform for the 5G mobile networks and beyond-is considered. The performance of the proposed GFDM-based relaying network with energy harvesting is studied in terms of the average BER for the general M-QAM constellation set. Numerical and simulation results are provided to give useful insights and to assess the accuracy of our mathematical derivations.
