Abstract

In this paper, energy efficiency (EE) and spectral efficiency (SE) in simultaneous wireless information and power transfer (SWIPT) systems are studied. First, unlike the concepts of EE and SE in conventional wireless communications, we propose four new definitions of EE and SE for SWIPT systems by taking account of two different applications of SWIPT. They are EE for information transfer, EE for energy harvesting, SE for information transfer, and SE for energy harvesting. Then, the transmit power and switching factor are selected as two key parameters influencing EE and SE in SWIPT. Finally, different EE-SE trade-off and optimization strategies are proposed for various working conditions. Numerical results verify that the proposed optimal system performance can be achieved by setting appropriate system parameters.
