Abstract
A multipath wideband communications receiver (100) having a plurality of RF signal paths (116, 136) covering different but overlapping frequency bands and a plurality of baseband signal paths (140, 150, 160, 170, 180, 190), the paths being re-configurable for sharing of the first and second paths in different ways in order to facilitate processing of received signals in different modes.Also, a rake receiver (800) employs a sigma-delta modulator arrangement (810) and programmable delays to provide fine delay adjustment. The sigma-delta modulator (810) may use sigma-delta circuitry from a sigma-delta A/D converters in a baseband paths of the receiver (100), that this may be achieved with no loss of functionality if in a particular reception configuration that sigma-delta A/D converter is not being utilized.
