Zusammenfassung:	This document discloses a solution for performing interference cancellation in a radio receiver. According to an aspect, there is provided a method for an apparatus of an access node, comprising: receiving, by the apparatus from a first radio unit of the access node via a first interface, a first spectrally whitened channel parameter and a first spectrally whitened data stream; receiving, by the apparatus from a second radio unit of the access node via a second interface, a second spectrally whitened channel parameter and a second spectrally whitened data stream; summing, by the apparatus, the first spectrally whitened channel parameter with the second spectrally whitened channel parameter and summing the first spectrally whitened data stream with the second spectrally whitened data stream; and extracting, by the apparatus, a desired data stream from the summed spectrally whitened data streams by using the sum of the first spectrally whitened channel parameter and the second spectrally whitened channel parameter.
