The continuous demand of increasingly high data rates services provided by wireless communications systems is contributing to saturate the RF spectrum. Visible Light Communication (VLC) systems try to alleviate this congestion by placing information transmission features alongside illumination systems. These systems have been proposed to make use of High-Brightness LEDs (HB-LEDs) to illuminate and to transmit with high power efficiency. The high bit rates achieved by VLC systems are based on…
