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

Mobile communications systems will evolve towards a third generation at the beginning of the new millenium. Third generation is built on the backward compatibility with the second generation networks. Thus wideband multi-standard receivers, which are able to operate according to multiple mobile communication standards, will be required by the third generation system users. This paper presents a number of system issues and design considerations which are involved in the design of wideband multi-standard DCS1800/UMTS digital receiver, and in particular the analog-to-digital converter (ADC) technology requirements for the implementation is presented.
