In full-duplex relays, simultaneous reception and transmission
in the same frequency results in self-interference which\ distorts the retransmitted signal and makes the relay prone\ to oscillation. We present an adaptive feedback canceller for\ multiple-input single-output (MISO) relays, efficiently combining\ spatial and temporal processing. The receive array is\ adaptively steered towards the minimum variance distortionless\ response (MVDR), whereas the temporal filter update is\ based on a novel low-complexity spectrum shaping scheme\ which avoids introducing additional delay in the relay station.
