High-speed digital signal processing for optical communications

Abstract

Todaypsilas electronic processing capability means that it is now possible to perform extensive signal processing at the highest commercial data rates. In this tutorial we discuss the design and technologies behind the use of signal processing for optical communications systems, and the choices available to the designer. Signal processing techniques, originally developed for wireless applications, are finding new uses, albeit at higher date rates, (and very much higher carrier frequencies) in the field of fibre-optic communications. Guided waves in fibre present new phenomena, which we must deal with in order to get the most out of this new application of technology.
