摘要： In a receive node (230) of a wireless network (100), an iterative multi-user multi-stage interference cancellation receiver (500, 1400, 1700) is used. The receiver (500, 1400, 1700) 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.

摘要： A base station herein assists a radio network controller (RNC) to allocate scrambling codes in a cell. The base station's assistance advantageously permits the RNC to allocate different length scrambling codes to different mobile terminals (or downlink carriers) in the cell. Specifically, the base station determines a preference for whether the length of a scrambling code to be allocated to each terminal or carrier should be short or long, based on whether uplink communications transmitted by the terminal, or downlink communications transmitted over the carrier, are to be processed with a high-complexity receiver or a low-complexity receiver. The RNC receives these preferences from the base station and takes them into account in order to allocate either a short scrambling code or a long scrambling code to each terminal or downlink carrier in the cell. The RNC then propagates the scrambling code allocations throughout the cell.

摘要： In a receive node (230) of a wireless network (100), an iterative multi- user multi-stage interference cancellation receiver (400, 800, 1100) 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 (400, 800, 1100) are adapted to reflect the changed interference characteristics.

摘要： It is presented a method, performed in a receiver device, for decoding transmissions of a set of coded information bits from a transmitter. The method comprises the steps of: deriving received symbols from first received data and second received data; converting the received symbols to sets of soft coded bit estimates; combining the sets of soft coded bit estimates to a combined set of soft coded bit estimates; decoding the combined set of soft coded bit estimates to a set of soft information bit estimates; converting the set of soft information bit estimates to a set of binary bits; determining whether the set of binary bits has been correctly or incorrectly decoded; performing interference cancellation on the received data; and repeating the mentioned steps until either the set of binary bits has been correctly decoded or a predefined maximum number of iterations is reached.

摘要： According to the teachings presented herein, a method and apparatus for communication signal processing advantageously use a mix of parametric and non-parametric correlation estimation in communication signal processing. Non-parametric estimation generates an "overall" correlation estimate for a received communication signal, and parametric estimation generates a "component" correlation estimate. The component correlation estimate is removed from the overall correlation estimate to form a partial correlation estimate that is used to process the received communication signal at least initially, such as in a pre-equalization stage. The overall and component correlation estimates are generated as impairment and/or data correlation estimates.

摘要： Systems and methods according to these exemplary embodiments provide for methods and systems for improving the signal-to-interference-plus-noise ratio (SIR) estimation between a mobile communications device and a base station (BS) for improving power control. A first SIR estimate is generated (802) based on signals received on at least a first channel and a second SIR estimate is generated (804) based on signals received on a second channel. A correction factor for the second SIR estimate is generated (806) based on at least the first SIR estimate, and the second SIR estimate is adjusted (808) with the correction factor. The first SIR estimate can, optionally, be generated using channel coefficients generated from signals received on both the first channel and the second channel.
