20130077657 | FINGER PLACEMENT IN MULTI-STAGE INTERFERENCE CANCELLATION - In a receive node of a wireless network, an iterative multi-user multi-stage interference cancellation receiver is used. After each stage of interference cancellation, interference characteristics change. An adaptive finger placement strategy is used in which after each stage of interference cancellation, finger delays and combining weights of the receiver are adapted to reflect the changed interference characteristics. | 03-28-2013 |
20130077670 | IMPAIRMENT COVARIANCE AND COMBINING WEIGHT UPDATES DURING ITERATIVE TURBO INTERFERENCE CANCELLATION RECEPTION - In a receive node of a wireless network, an iterative multi-user multi-stage interference cancellation receiver is used. After each stage of interference cancellation, interference characteristics change. An adaptive strategy is used in which after each stage of interference cancellation, impairment covariance is parametrically updated and combining weights of the receiver are adapted to reflect the updated impairment covariance. | 03-28-2013 |
20130077720 | MULTI-STAGE TURBO EQUALIZATION AND INTERFERENCE CANCELLATION RECEIVER FOR WIRELESS SYSTEMS - In a receive node of a wireless network, an iterative multi-user multi-stage interference cancellation receiver is used. The receiver performs code-averaged equalization and chip chip-level code-specific interference over-cancellation on the received signals. This can result in a unified interference cancellation processing, and can avoid cumbersome calculations of code cross correlations that is required in symbol-level interference cancellation. A symbol-level code-averaged desired signal add-back is performed to address the over-cancellation of some desired signals. | 03-28-2013 |
