Abstract
This paper puts in Cascade the power line communications
(PLC) channel and the visible light communications
(VLC) channel, in order to use the PLC channel as backbone for
the VLC channel. This combination is suitable for applications
in which hybrid PLC-VLC systems are needed. We investigate
the behaviour of the cascaded channels for a full link transmission.
Quadrature phase shift keying combined with orthogonal
frequency division multiplexing (QPSK-OFDM) is used over the
PLC channel and color shift keying (CSK) is deployed over
the VLC channel to convey the information. Cascaded channel
variances are analyzed. Complete simulated bit error rate (BER)
is analyzed and presented for multiple scenarii that could occur
in the two channels.
