Wideband digital receivers for multi-standard software radios

Abstract

Multi-standard software-definable radios which are capable of operation according to a variety of different mobile radio standards represent an extremely powerful tool for evolution towards future third-generation cellular systems. This is particularly the case in Europe where the emergence of advanced UMTS air-interfaces needs to be accompanied with some degree of backward compatibility with the well-established GSM/DCS systems. This paper examines a number of the architectural issues and trade-offs involved in the design of wideband multi-standard GSM/UMTS digital radios and presents an examination of the filtering and ADC technology requirements for their implementation. This work has been undertaken in the context of the FIRST project (Flexible Integrated Radio System Technology) as part of the ACTS mobile line.

System design considerations of wideband multi-standard receiver for 3rd generation mobile system applications

“…For example, UMTS system is intended to work with the current Global System for Mobile Communications (GSM). Therefore, it is important to develop the 3G terminal that can be used as a multi-standard transceiver [ 12], [7].…”

Next generation wideband multi-standard digital receiver design

“…This lack of unity has raised a myriad of distressing concerns for network providers, engineers and consumers, and stymied the rapid adoption of each subsequent generation of cellular technology. As a means of meeting this challenge, effort is now being devoted to the development of integrated radio receivers that support multiple standards [2], [3].…”
