Abstract
Embodiments are provided to enable effective cancellation or reduction of the self-interference (SI) introduced when applying full-duplex transmission to MIMO systems. A method embodiment includes forming, using a first component matrix of a precoding matrix generated in accordance with signal channel conditions, a plurality of beams for a plurality of transmit signals, and forming, using a second component matrix of the precoding matrix, a plurality of SI cancellation signals corresponding to the transmit signals. The first component matrix is arranged to maximize a sum-rate of transmissions in the transmit signals assuming zero SI in the network component. The second component matrix is arranged to maximize SI suppression in a plurality of receive signals in the network component. The beams are transmitted at a plurality of antennas, also used to receive the receive signals. The SI cancellation signals are added to the receive signals to detect corrected receive signals.
