DATA CONVERSION IN ADVANCED COMMUNICATION SYSTEMS

A. Moschitta, D. Petri

Abstract

This paper presents an overview of state of the art applications of Digital to Analog and Analog to Digital converters when embedded into a Digital Communication System (DCS). Three DCSs are considered: the Terrestrial Digital Video Broadcasting (DVB), the Digital Audio Broadcasting (DAB), and the Global System for Mobiles (GSM). For each system the role of converters is identified, along with the minimal performance requirements. The advantages of Sigma-Delta converters upon traditional converters are then outlined and the usage of Sigma-Delta converters is discussed as a mean to improve performances of DCSs.
