Claim 11:
12. A control device for mitigating interference in a network node, the control device is configured to:
receive radio signals comprising at least one desired signal and interference;
estimate 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;
determine 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
apply the interference suppression matrix on the received radio signals to mitigate the interference from the received radio signals.
