Abstract

Example embodiments relate to a computer-implemented method for reducing self-interference (130) from a transmitter array (220, 250) at a receiver array (230, 260), the computer-implemented method comprising: generating (201) a set of beamforming antenna pairs (210) by selecting at least two non-identical antenna pairs (214, 215) from transmitter antennas (221 - 223) within the transmitter array (220) or from receiver antennas (261, 262, 263) within the receiver array (260); determining (202) a null space of the self-interference (217) at the receiver array (230, 260) comprising null space vectors (216) of the respective beamforming antenna pairs (211 - 213); and determining (203) beamforming coefficients (218) for the respective antennas within the set of beamforming antenna pairs (210) that reduce self-interference at the receiver array based on a linear combination (219) of the null space vectors (216) of the respective beamforming antenna pairs (211 - 213).
