Abstract

The transition between the second and third generation of mobile communications services can be significantly facilitated by the design of reconfigurable mobile phones. This paper presents an architecture for dual standard receptors, which uses a reconfigurable sigma delta modulator for digitalization at intermediate frequency or at baseband. The proposed approach has been compared with the existing methods. High level simulations show its feasibility.
