Method And Apparatus For Combining Weight Computation In A Ds-Cdma Rake Receiver

US Patent:
7397842, Jul 8, 2008
Filed:
Sep 26, 2003
Appl. No.:
10/672127
Inventors:
Gregory E. Bottomley - Cary NC, US
Carmela Cozzo - Cary NC, US
Ali S. Khayrallah - Cary NC, US
Dignus-Jan Moelker - Amsterdam, NL
Assignee:
Telefonaktiebolaget LM Ericsson (publ)
International Classification:
H04B 1/00
US Classification:
375148, 375130, 375134, 375136, 375137, 375142, 375143, 375144, 375147, 375150, 375152, 375346
Abstract:
A RAKE receiver circuit generates combining weights based on channel estimates and combining statistics that comprise channel coefficient statistics, noise statistics, and channel estimation error statistics. Together, these statistics incorporate the relationships in noise and channel estimation across two or more RAKE fingers, and thus improve combining weight generation. Exemplary determination of statistics comprises channel coefficient cross-correlations, noise cross-correlations, and channel estimation error cross-correlations. Determination of the statistics can be varied based on, for example, the assumption of default or nominal signal models. Further, statistics determination can be configured for different receive and transmit diversity scenarios, wherein combining statistics can be determined on a per diversity signal basis, or jointly for two or more diversity signals, or in a mixed separate/joint method wherein one or more statistics are determined on a per signal basis and one or more statistics are determined across the signals.

Method For Path Searching And Verification

US Patent:
7460583, Dec 2, 2008
Filed:
Dec 15, 2003
Appl. No.:
10/736122
Inventors:
Ali S. Khayrallah - Cary NC, US
Carmela Cozzo - Cary NC, US
Gregory E. Bottomley - Cary NC, US
Assignee:
Telefonaktiebolaget LM Ericsson (publ) - Stockholm
International Classification:
H04B 1/00
US Classification:
375148
Abstract:
The present application describes a new path search and verification method and apparatus for identifying and selecting one or more delays for a receiver. A front-end receiver receives a signal having one or more signal images, where each signal image has a corresponding signal delay. A tree generator builds a hierarchical delay tree from a plurality of delay nodes, each corresponding to one of the signal delays. A tree searcher searches through the delay tree to identify one or more surviving delay nodes, where each surviving delay node corresponds to a candidate delay for the receiver. The receiver may also include a state machine comprising a plurality of ordered states for providing candidate delays for the receiver. The state machine stores the candidate delays and shifts the candidate delays between states within the state machine based on the latest results from the tree searcher.

Method And Apparatus For Finger Placement In Rake Receiver

US Patent:
7469024, Dec 23, 2008
Filed:
Sep 2, 2003
Appl. No.:
10/653679
Inventors:
Ali S. Khayrallah - Cary NC, US
Carmela Cozzo - Cary NC, US
Gregory E. Bottomley - Cary NC, US
Assignee:
Telefonaktiebolaget LM Ericsson (publ) - Stockholm
International Classification:
H04B 7/10
US Classification:
375347, 375267
Abstract:
A receiver based on a RAKE receiver architecture includes a logic circuit configured to assign one or more RAKE fingers to a finger placement grid that is independent from a searcher delay grid used by the receiver's searcher in generating multipath delay profiles for received signals. The logic circuit may use the multipath delay profile to “tune” the finger placement grid relative to the searcher delay grid but the delay resolution of the finger placement grid is independent of the searcher delay grid. This independence permits, for example, setting the finger placement grid to a delay resolution based on a Nyquist criterion independently from the delay resolution used by the searcher. The receiver may use two or more finger placement grids, may operate in a mixed mode where fingers are assigned on- and off-grid, and may operate selectively in grid or non-grid modes.

Parameter Estimate Initialization Using Interpolation

US Patent:
7558533, Jul 7, 2009
Filed:
Nov 7, 2007
Appl. No.:
11/936193
Inventors:
Carmela Cozzo - Cary NC, US
Gregory Bottomley - Cary NC, US
Rajaram Ramesh - Cary NC, US
Assignee:
Telefonaktiebolaget L M Ericsson (Publ) - Stockholm
International Classification:
H04B 15/00
US Classification:
455 65, 455137
Abstract:
A receiver is described herein that is capable of receiving and processing a radio signal and further capable of using interpolation to initialize receiver parameters when there is a change in at least one delay associated with the received radio signal or when there is at least one new correlator position. For instance, the receiver parameters that can be initialized include: (1) channel coefficients; (2) AFC parameters; (3) tracking parameters; (4) noise statistics (noise correlations); (5) signal statistics (channel coefficient correlations); (6) data statistics (despread values or chip samples); or (7) combining weights.

H{dot over (a)}kan B. Eriksson - Täby, SE
Carmela Cozzo - Cary NC, US
Assignee:
Telefonaktiebolaget L M Ericsson (Publ) - Stockholm
International Classification:
H04B 1/00
US Classification:
375142, 375140
Abstract:
A Direct-Sequence Code Division Multiple Access (DS-CDMA) receiver and method of allocating probing correlators and combining correlators (fingers). A front-end processor converts received radio signals to baseband samples. Based on average path strengths, a controller adaptively allocates probing correlators to signal paths to de-spread certain received signals. Based on path power estimates, the controller adaptively allocates combining correlators to signal paths. The allocations may be made to minimize the total received power at the receiver, or to achieve acceptable performance for all users.

Method And Apparatus For Iteratively Calculating Channel Response Estimates

US Patent:
7724841, May 25, 2010
Filed:
Oct 3, 2006
Appl. No.:
11/538074
Inventors:
Gregory E. Bottomley - Cary NC, US
Carmela Cozzo - Cary NC, US
Assignee:
Telefonaktiebolaget LM Ericsson (publ) - Stockholm
International Classification:
H04L 27/00
US Classification:
375316
Abstract:
Channel response and impairment correlation estimates are iteratively determined. According to one embodiment of performing channel estimation for use in received signal processing, a channel response estimate is calculated based on an initial impairment correlations estimate and a measured channel response derived from a received signal. A revised impairment correlations estimate is calculated using a parametric approach based on the channel response estimate and the channel response estimate is recalculated based on the revised impairment correlations estimate. According to one embodiment of a wireless communication device, the device comprises a parameter estimation unit configured to iteratively calculate a medium channel response estimate based on a parametric impairment correlations estimate and a measured net channel response derived from a received signal. The wireless communication device also comprises circuitry configured to control how many times the parameter estimation unit calculates the medium channel response estimate.

Method And Apparatus For Selecting Signal Processing Delays Based On Historical Selection Data

US Patent:
7751467, Jul 6, 2010
Filed:
Dec 4, 2006
Appl. No.:
11/566256
Inventors:
Carmela Cozzo - Cary NC, US
Gregory E. Bottomley - Cary NC, US
Assignee:
Telefonaktiebolaget LM Ericsson (publ) - Stockholm
International Classification:
H04B 1/00
US Classification:
375150, 375136
Abstract:
Signal processing delays are selected from a candidate set in a wireless receiver based on both present and past channel behavior. According to one embodiment, a subset of signal processing delays are selected for received signal processing by accumulating a history of periodic delay selection computations for a candidate set of signal processing delays during a time interval. The delay selection calculations are based on cross-correlations between different ones of the signal processing delays. At the end of the time interval, a subset of the signal processing delays are selected from the candidate set of delays for received signal processing based on the history of delay selection computations.
