    Abstract: For determining paths in the scope of a multipath search, a device for use in a wireless communications system performs: obtaining a delay profile of a code division multiple access transmission signal, the delay profile being in a form of complex symbols, each complex symbols resulting from a despreading of said received signal after being delayed by a distinct delay; comparing the real part of said complex symbols forming the delay profile with a first threshold, the first threshold being determined on the basis of a noise level determined by the imaginary part of said complex symbols forming the delay profile; and determining said paths on the basis of the comparing.

    Abstract: 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.
