Abstract

Wireless power transfer technologies such as simultaneous wireless information and power transfer (SWIPT) have shown significant potentials to revolutionise the design of future wireless communication systems. When the only energy source is the wireless signals that are mainly intended for information communications, the sustainability and outage performance of SWIPT systems become critical for theoretical evaluation and practical applications. This paper firstly models the energy harvest and consumption of power splitting based SWIPT systems to establish the general sustainability condition. We further model the power and information transfer outages using Markov Chain, which are unique for SWIPT systems since both factors could cause communication outage. We further demonstrate how to apply the closed-form expression for the outage to optimize the key parameter of splitting ratio for PS based SWIPT systems. Hardware and numerical experiments demonstrate the validity of the proposed model and outage analysis, and confirm the effectiveness of the solution to calculate the optimal splitting ratios under different signal and channel conditions.
