Abstract :
This paper analyses the merits of adaptive threshold detection (ATD) over fixed threshold detection (FTD) as a means to reduce the impact of ambient shot noise on wireless infrared communication links. Original analytic details are provided to allow for an accurate sensitivity account of an optical wireless receiver that employs either ATD or FTD. Proposals towards the implementation of adaptive threshold detection are outlined with considerations on their respective benefits and drawbacks
