Abstract
A multipath wideband communications receiver () having a plurality of RF signal paths () covering different but overlapping frequency bands and a plurality of baseband signal paths (), 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 () employs a sigma-delta modulator arrangement () and programmable delays to provide fine delay adjustment. The sigma-delta modulator () may use sigma-delta circuitry from a sigma-delta A/D converters in a baseband paths of the receiver (), 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.
