    Abstract: A technique for allocating fingers in a path searcher of a multipath receiver involves determining a required number of fingers for each multipath region, determining a number of allocated fingers for each multipath region according to an area-based weighting scheme such that each multipath region that is allocated fewer than its required number of fingers is deemed to have a non-zero residual area, allocating any surplus fingers to multipath regions having non-zero residual areas until either no surplus fingers remain or each multipath region is allocated its required number of fingers, and placing any fingers allocated to each multipath region within the multipath region. Placing the fingers in un-resolvable path scenario involves detecting path location at the edges of multipath region; placing fingers at the edges and placing remaining fingers uniformly between the first and the last path such that the there is a minimum placement separation between the fingers.

    Abstract: A plurality of fingers 12 separately demodulate reception signals of a plurality of paths transmitted from a plurality of terminals. A first rake combining unit 13a combines a plurality of demodulated signals corresponding to a first transmission terminal from among the signals demodulated by the fingers 12. A second rake combining unit 13b combines a plurality of demodulated signals corresponding to a second transmission terminal from among the signals demodulated by the fingers 12. A change-over switch 16a connects a finger 12-8 from among the fingers 12-1 to 12-32 to either of the first rake combining unit 13a and the second rake combining unit 13b in a switchable manner. Therefore, a plurality of users can use a single finger in a switchable manner.

    Abstract: An apparatus and method for demodulation of a composite signal containing a plurality of multi-path components use a virtual finger. The method includes buffering digital samples of a signal into a first memory element, randomly accessing the digital samples from the first memory element to correlate a particular multi-path component from the signal, and iteratively accumulating the correlated particular multi-path component into a second memory element.

    Abstract: A device includes a request arbitration unit that (1) receives a number of requests for PN vectors from a number of processing units and (2) provides a control indicative of each request selected for processing. An address generator provides one or more addresses (which may be dependent on a particular PN sequence being requested and the offset of the PN sequence) for each selected request. One or more memory units store all nullbasenull PN sequences (e.g., and X(i) sequence and a Y(i) sequence defined by W-CDMA) that may be used to generate all requestable PN vectors. The memory unit(s) provide one or more segments of one or more base PN sequences, based on the address(es). A buffering unit provides a set of one or more PN vectors derived from the one or more PN segments for each selected request.
