- Abstract
- In this letter, we propose a novel simultaneous wireless information and power transfer (SWIPT) scheme, namely the frequency-splitting (FS) SWIPT, which separates the power and data signals in the frequency domain. The proposed FS SWIPT scheme is advantageous in that it can maximize the efficiency of the high power amplifier (HPA) in the transmitter and reduce the harmonic distortion caused by the nonlinearity of the HPA. We design a receiver circuit for the FS SWIPT by using a circulator and filters. We analyze the FS and conventional power-splitting (PS) SWIPT schemes in consideration of the nonlinearity of the HPA. We show that the proposed FS SWIPT greatly outperforms the PS SWIPT in terms of the harvested power and signal-to-noise ratio (SNR).
