    • The invention provides a method for self-interference suppression in a multi-antenna device that is part of a communication channel between a transmitter and a receiver of a wireless communication system. The communication system uses the multi-antenna device, the multi-antenna device is located between the transmitter and the receiver and uses antennas and a relay unit forwarding signals from the transmitter to the receiver. The communication channel has a transmit channel, defined by a transmit channel matrix between the transmitter and the multi-antenna device, a receive channel defined by a receive channel matrix, between the multi-antenna device and the receiver and a self-interference channel between an output and an input side of the multi-antenna device. The self-interference channel is defined by a self-interference channel matrix wherein the method comprises the steps of: • quipping the multi-antenna device with at least three antennas and; • suppressing the self-interference channel by using at least one filtering matrix arrangement being inserted between the antennas and the relay unit. The invention also provides a node in a wireless communication system comprising the multi-antenna device for self-interference suppression in the multi-antenna device module that is part of a communication channel.
