Information and Energy Cooperation in OFDM Relaying: Protocols and Optimization.

Integrating power transfer into wireless communications to support simultaneous wireless information and power transfer (SWIPT) is a promising technique in energy-constrained wireless networks. While most existing work on SWIPT focuses on capacity-energy characterization, the benefits of cooperative transmission for SWIPT have been investigated far less. In this paper, we consider SWIPT in an orth...
