Design of optical matched filters

P.A. Humblet

Abstract

A study is made of the design and the performance of receivers using optical matched filters and direct detection, when the basic pulse shape consists of a rectangular pulse of monochromatic light. The modulation format can be ASK (amplitude-shift keying), FSK (frequency-shift keying), or DPSK (differential phase-shift keying). Such receivers are useful when amplifier noise is the main source of uncertainty as they optimally reject additive white Gaussian noise. The performances of ASK and FSK receivers are reported, taking into account shot noise and the effects of postdetection filtering.>
