Abstract
In visible light communications (VLC) technology,
the channel is generally modeled as a multi-path propagation
environment. This is due to the presence, on the photo-detector
(PD), of specular and non-specular signal components. The
Racian K-factor is exploited in such environments to measure
the dominance of the line-of-sight (LoS) signal power over that
of the non-LoS (NLoS) link. In this paper, K is exploited in
the evaluation of the VLC link. Examples of the use of K is
underlined in the computation of few link evaluation metrics
including the signal-to-noise ratio (SNR),
, the channel capacity,
C, and the outage probability
