Abstract
The intelligent reflecting surface (IRS) and angle diversity receiver
(ADR) jointly assisted indoor visible light communication (VLC) system
is proposed to improve average signal-to-noise ratio (ASNR)
performance. Specifically, to maximize the ASNR at the receiving
plane, the roll angle and yaw angle of IRS and the inclination angle
of the side detector in the ADR structure are optimized simultaneously
as one non-convex problem. With the bat algorithm, the optimal
solution is numerically obtained. Results show that when the transmit
power of the light emitting diode lamp array is 1 W, the ASNRs
of this VLC system optimized by IRS and ADR are approximately
7.89 dB, 3.58 dB, and 2.09 dB higher than those
of the original, IRS-assisted, and ADR-assisted VLC systems,
respectively. Furthermore, the transmission rate and bit error rate
performances of the original, IRS-assisted, ADR-assisted, and IRS and
ADR jointly assisted indoor VLC systems are also simulated and
compared; it is found that the performance improvement of the indoor
VLC system jointly optimized by IRS and ADR is more evident than that
of the other three VLC systems. This study will benefit the research
and development of indoor VLC systems.
