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.
