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.

Abstract: A Node-B/base station has a path searcher and at least one antenna for receiving signals from users. The path searcher comprises a set of correlators. Each correlator correlates an inputted user code with an inputted antenna output of the at least one antenna. An antenna controller selectively couples any output of the at least one antenna to an input of each correlator of the set of correlators. A code phase controller selects a user code for input into the set of correlators. Each delay of a series of delays delays the selected user code by a predetermined amount and each correlator of the set of correlators receives a different code phase delay of the selected user code. A sorter and path selector sorts the output energy levels of each correlator of the sets of correlators and produces a path profile for a user based on the sorted output energy levels.

Abstract: A Node-B/base station has an access burst detector. The access burst detector comprises at least one antenna for receiving signals from users and a pool of reconfigurable correlators. Each correlator correlates an inputted access burst code at an inputted code phase with an inputted antenna output. An antenna controller selectively couples any output of the at least one antenna to an input of any of the correlators. A code controller 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 sorts output energy levels of the correlators.
