Energy-efficient Full-duplex Transmission Strategy Design with SWIPT

This paper designs an energy-efficient transmission strategy to maximize energy efficiency (EE) of relay networks with simultaneous wireless information and power transfer (SWIPT). In the designed transmission strategy, all the transmission nodes are full-duplex nodes and direct links are existed between the end nodes to transmit more signals. At the same time, one of the end nodes transmits signal with SWIPT to extend network lifetime. What's more, the nodes' transmission powers are optimally allocated by our proposed alternating optimal algorithm to maximize EE. Simulations show that the EEs of the relay networks can be improved with our designed transmission strategy.
