Abstract :
The future development of mobile terminals will be driven by the enormous service potential of next generation systems and by the need to continuously widen the users choice with respect to access, service, and content by means of any terminal equipment. In order to fit to these requirements novel architectural concepts for wireless systems are needed. In this contribution a flexible, digital receiver architecture with highly optimized components is introduced. It is shown how the A/D-converter and the filtering stages, which are the most critical components in such a receiver, can be optimized by using a properly designed ΔΣ-modulator and novel digital filtering stages. These filtering stages perform decimation and channel selection together and consist of a special class of wave digital filters. Due to this concept a number of advantages are obtained and a very efficient realization in VLSI-technology becomes feasible.
