  Abstract

We propose an SNR-based power splitting receiver structure for Simultaneous Wireless Information and Power Transfer (SWIPT) in adaptive modulation systems which achieves improved rate-energy performance. The proposed scheme determines a power splitting ratio in order to achieve both the maximum discrete-rate spectral efficiency and maximum average harvested energy. In this paper, we verify that the proposed scheme has the same discrete-rate spectral efficiency that the conventional adaptive modulation systems can achieve, and derive the average harvested energy in the Rayleigh fading channel. We compare the discrete-rate spectral efficiency of the proposed scheme with that of the conventional adaptive modulation systems and verify that the analyzed average harvested energy performance is valid comparing with the simulation results.
