Abstract
A plethora of physical-layer techniques aim to enhance the
performance of communication systems in several ways. Spectral efficiency
and security are on the top of the list of enhancements; however, both are
isolated and antagonistic islands of research. Augmented communication
(ACom) is introduced in this Letter as the first technique that aims to
combine these two enhancements in visible light communications (VLCs). The
dividends of the proposed concept are demonstrated via simulations and the
performance is experimentally validated. Results show that ACom can
simultaneously provide the high spectral efficiency and the resistance to
eavesdropping, while introducing minimal signal-to-noise ratio
penalties.
