Patent number: 7630690Abstract: 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.Type: GrantFiled: April 11, 2003Date of Patent: December 8, 2009Assignee: InterDigital Technology Corp.Inventors: John David Kaewell, Jr., Timothy Berghuis, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward L.

Patent number: 7092432Abstract: 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.Type: GrantFiled: May 4, 2004Date of Patent: August 15, 2006Assignee: InterDigital Technology CorporationInventors: John David Kaewell, Jr., Timothy Berghius, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward Hepler, Michael Koch, William C.

Patent number: 7082286Abstract: 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.Type: GrantFiled: April 11, 2003Date of Patent: July 25, 2006Assignee: InterDigital Technology CorporationInventors: John David Kaewell, Jr., Timothy Berghuis, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward L.

Patent number: 7017103Abstract: A Viterbi equalizer for equalization of a data signal transmitted via a channel that is subject to interference has at least one add-compare-select unit (ACS), which carries out an ACS operation for each channel state in a time step k. Furthermore, the equalizer has a unit for calculating metric increments in advance and for storing the metric increments. The calculation unit calculates in advance the metric increments relating to all the transitions from a state which can be predetermined in the time step k to the states which can be reached by the transitions in the time step k+1. The metric increments are retained in an output memory such that they can be called up for utilization in the ACS unit.Type: GrantFiled: January 3, 2003Date of Patent: March 21, 2006Assignee: Infineon Technologies AGInventors: Peter Bohnhoff, Burkhard Becker, Bin Yang

Patent number: 6954507Abstract: In a radio receiver, an equalizer generates reliability information in the form of soft decision information indicating probabilities that a data symbol received by the radio receiver is based on a specific transmitted value. A bit error rate estimator obtains bit error rate information regarding the bit error rate of the received signal, corresponding to the received data symbols, by evaluating the reliability information.Type: GrantFiled: March 11, 2002Date of Patent: October 11, 2005Assignee: Infineon Technologies AGInventors: Peter Bohnhoff, Ralf Hartmann
