Paper Abstract

This paper deals with filtering techniques, both optical and electrical for suppressing background light interference in a wireless infrared (IR) diffuse-light channel, operating in closed working areas. Edge and bandpass optical filters are discussed, and a variety of electrical filtering circuits is presented covering low, medium, and high bit-rates that may be required by an IR system, depending on its application.
