Abstract
This paper presents the implementation of an
integration technique used to combine power line commu-
nications (PLC) and visible light communications (VLC)
channels in inter-building scenarios. It considers the narrow
band PLC (NBPLC). Phase-shift keying (PSK) is used to
convey the information over the PLC link and colour shift
keying (CSK) technique is used on the VLC link. The colour
wheel method is exploited to map PSK symbols to colours.We
define a parameter x, which represents different magnitudes
of the PSK complex symbol observed over the PLC channel.
x is adjusted to an optimal value to meet the requirement
of the CSK design. The bit error rate (BER) is analysed
and the performance of the system is presented for multiple
values of the modulus of the detected PSK symbol. A practical
implementation is performed to verify the PSK-CSK mapping
method. The impact of the sun’s rays on the red-green-blue
(RGB) symbols is analysed and the interference source is highlighted.
