Abstract
The invention relates to a method for tracking closely adjacent and time-shifted signals incoming to a RAKE-receiver (25). According to the method, the sampling positions of the RAKE-branches (25a, 25b) are not permitted to come closer to one another in time than by a predetermined minimum value when updating the branches. The invention also relates to an arrangement (24) for putting the method into effect. The arrangement includes a search unit (24a), a plurality of tracking units (24c, 24d) and a processor unit (24b). The invention also relates to a RAKE-receiver utilizing said apparatus.
