Abstract (en)

[origin: WO2013048326A2] 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 strategy is used in which after each stage of interference cancellation, impairment covariance is parametrically updated and combining weights of the receiver (400, 800, 1100) are adapted to reflect the updated impairment covariance.
