NettetThe capability of reducing the intensity of output light is called dimming. LEDs can be dimmed by controlling the forward current flowing through them. This can be achieved in two ways: Amplitude ... The higher the duty ratio is, the brighter the LED will appear to the observer due to higher average forward current being supplied to the LED. NettetIn this paper, we address the design of multi-user multiple-input single-output (MU-MISO) precoders for indoor visible light communication (VLC) systems. The goal is to minimize the transmitted optical power per light emitting diode (LED) under imperfect channel state information (CSI) at the transmitter side. Robust precoders for imperfect CSI available …
