Abstract: A Node-B/base station comprises a plurality of antennas (28I - 28M) for receiving user signals and a path searcher. The path searcher comprises a set of correlators (42-1, 42-2 … 42-P). Each correlator of the set of correlators correlates an inputted user code with an inputted antenna output. An antenna controller selectively couples an output of one of the plurality of antennas to an input of each.

Abstract: A Node-B/base station has an access burst detector. The access burst detector comprises at least one antenna (28 1 -28 M ) for receiving signals from users and a pool of reconfigurable correlators, implemented in ASIC. Each correlator (36 1 -36 O ) correlates an inputted access burst code at an inputted code phase with an inputted antenna output. An antenna controller (30) selectively couples any output of the at least one antenna to an input of any of the correlators. A code controller (32) provides to an input of each correlator an access burst code. The code controller controls the inputted code phase of each controller. A sorter/post processor (38) sorts output energy levels of the correlators.

Abstract: A Node-B/base station receiver comprises at least one antenna for receiving signals. Each finger of a pool of reconfigurable Rake fingers recovers a multipath component of a user and is assigned a code of the user, a code phase of the multipath component and an antenna of the at least one antenna. An antenna/Rake finger pool interface provides each finger of the Rake pool an output of the antenna assigned to that Rake finger. A combiner combines the recovered multipath components for a user to produce data of the user.

Abstract: Apparatus and method for correlating a received communication of a known sequence over a wireless channel through the use of a finite impulse response (FIR) filter (24) having a small number of taps to reduce hardware requirement by as much as one-half that of conventional techniques while obtaining amplitude degradation which is no worse than experienced when employing conventional techniques.
