Summary:To cope with the requirements of future mobile systems, the terminals must become more flexible with respect to multi-standard and multi-service capabilities. The flexibility and the degree of integration can be increased by replacing analogue by digital signal processing. To account also for the stringent cost and low power requirements the digital signal processing in such a concept must be optimized for a hardware efficient VLSI-implementation. In this contribution the digital signal processing for a flexible and optimized receiver architecture will be considered. It consists of an optimized digital mixer and novel high-order, programmable decimation filters. For the lower decimation filter stages a structure of cascaded low-order wave digital lattice filters will be proposed. The use of this filter type results in a number of advantages compared to state of the art solutions.
