With full-duplex relays, simultaneous reception and transmission in
the same frequency produce self-interference distortion and relay oscillation,
hampering reception at the receiver end unless properly
mitigated. Previous adaptive methods for self-interference cancellation
using multiple receive antennas require knowledge of the direction
of arrival of the source signal. We present a novel architecture
and adaptive scheme for Amplify-and-Forward relays allowing cancellation
without such knowledge. The temporal filter is updated
under the property restoral paradigm in order to match the power
spectrum of the retransmitted signal to that of the source signal.
