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.
