Estimation and Compensation of Total Harmonic Distortion in SWIPT

Abstract

Simultaneous Wireless Information and Power Transfer (SWIPT) system is a feasible technology for the next-generation wireless communication system. The crucial problem encountered by the SWIPT system during practical deployment is hardware impairment. So, this article analyses the impact of total harmonic distortion in SWIPT systems. Here we consider the harmonic distortion in a realistic SWIPT HPA transmitter model that follows M-ary modulation. The SWIPT receiver employs power-splitting architecture. We analyse the harvested energy and the Signal to Noise Ratio of the received signal with and without harmonic distortion. For the maximum applied amplifier input signal power of 1dBm, harvested energy of 13dBm and SNR of 20dB is obtained.
