Claim 0:
1. A method for mitigating interference in a network node, the method being performed by a control device, the method comprising:
receiving radio signals comprising at least one desired signal and interference
estimating a characteristic of the interference;
wherein the estimation comprises calculating correlation statistics of power levels of frequency sub-bands comprising the interference with frequency sub-bands comprising the received radio signals;
determining an interference suppression matrix to suppress the interference in the frequency sub-bands of the received radio signals based on the estimated characteristic of the interference;
wherein the interference suppression matrix is further determined based on information from inter-band interference observed across distinct sub-bands of the received radio signals, and
applying the interference suppression matrix on the received radio signals to mitigate the interference from the received radio signals.
