The present solution relates to a method in a communication node (201, 204, 210, 213) for canceling interference between a plurality of signals in a communication system (200). The communication node receives (501), at each of a plurality of receiver antennas (407), a respective signal. The communication node (201, 204, 210, 213) cancels (502) a first part of interference between the plurality of received signals. Then, the interference cancelled signals and the received signals are filtered (504) before a second part of interference between the filtered signals is cancelled (505).
