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: A Node-B/base station has an access burst detector. The access burst detector comprises at least one antenna (281…28m) for receiving signals from users and a pool of reconfigurable correlators (361…360). Each correlator 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 (40) provides to an input of each correlator an access burst code. The code controller (40) 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 (2811-28MN). Each finger of a pool of reconfigurable Rake fingers (320-323) 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 (30) 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: A wireless transmit receive unit (WTRU) and methods are used in a wireless communication system to process sampled received signals to establish and/or maintain wireless communications. A selectively controllable coherent accumulation unit produces power delay profiles (PDPs). A selectively controllable post processing unit passes threshold qualified magnitude approximation values and PDP positions to a device such as a rake receiver to determine receive signal paths.
