摘要：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 areceiver of a wireless communication system. The communication system uses the multi-antenna device, the multi-antenna device is located between the transmitter and thereceiver and uses antennas and a relay unit forwarding signals from the transmitter tothe receiver. The communication channel has a transmit channel, defined by a transmitchannel matrix between the transmitter and the multi-antenna device, a receive channeldefined by a receive channel matrix, between the multi-antenna device and the receiverand a self-interference channel between an output and an input side of the multi-antennadevice. The self-interference channel is defined by a self-interference channel matrixwherein the method comprises the steps of: • quipping the multi-antenna device with atleast three antennas and; • suppressing the self-interference channel by using at leastone filtering matrix arrangement being inserted between the antennas and the relay unit.The invention also provides a node in a wireless communication system comprising themulti-antenna device for self-interference suppression in the multi-antenna devicemodule that is part of a communication channel.
