Performance Analysis of 8-bit ODACs for VLC Applications

Performance Analysis of 8-bit ODACs for VLC Applications

A discrete optical power level stepping technique in visible light communication (VLC), also known, as an optical digital to analog conversion (ODAC) has been proposed. This is an alternative concept for VLC front-end design, able to mitigate the LED intrinsic non-linearity. Additionally, it removes...
