Abstract
Visible Light Communications (VLC), which is expected to provide wireless communications and illumination facilities together, is earning increasing attention. However, it is hard to obtain satisfyingly uniform signal quality at the receiving terminal even for locations within the same room by Komine et al. in Asia-Pacific conference on communication (APCC 05), IEEE Press, Perth, pp 294–298 (2005). In this letter, an evolutionary algorithm-based optimization scheme is proposed as a candidate approach for VLC to reduce the variability of the received power. The presented results based around the use of a commercially available detector with a FOV = 45º. show that the dynamic range of received power can be reduced to 34% against the peak optical power from 52% while the impact on illuminance function is negligible.
