Performance analysis of the power splitting simultaneous lightwave information and power transfer (PS-SLIPT) architecture

Abstract

Recent studies done on Simultaneous Lightwave Information and Power Transfer (SLIPT) has become a hot topic among the research community. The importance of the SLIPT is to harvest energy using light sources while decoding the information. In this thesis work, we present the mathematical framework for the Power Splitting (PS) based SLIPT system and study the performance of the PS-SLIPT and Time Splitting (TS)-SLIPT architectures. Moreover, we quantitatively study the harvested energy with different Field of View (FoV) angles of the Light Emitting Diode (LED) and the Photodiode (PD). In addition, analyze the important parameter of the Visible Light Communication (VLC) system to achieve maximum received power and we consider the amount of harvested energy for different Direct Current (DC) values. Overall, concludes that the Field of View (FoV) and DC bias signals are directly affected by SLIPT systems. Using numerical simulations, we demonstrate the performance of the both architectures to enhance the QoS of information decoding data rate, amount of harvested energy and trustworthiness of the information. Further, our research work extend to Simultaneous Wireless Information and Power Transfer (SWIPT) technique is introduced in Radio Frequency (RF) communication to carry both information and power in same medium. In this approach, the energy can be harvested while decoding the information carries in an RF wave. Recently, the same concept apply in VLC namely SLIPT, which is highly recommended in an indoor applications to overcome the problem facing in RF communication. Thus, the SLIPT is introduce to transmit the power through a Light Emitting Diode (LED) luminaries. In this work, we compare both SWIPT and SLIPT technologies and realize SLIPT technology archives increase performance in terms of the amount of harvested energy, outage probability and error rate performance.
