Popis: The key enabling technology to in-band full duplex wireless is the self-interference cancellation. This paper proposes a realtime software defined digital self-interference cancellation based on machine learning. The contributions of this work include: (1) a digital self-cancellation scheme that approaches to the limit of the hardware, and (2) an open software defined cancellation framework that supports the realtime cancellation using machine learning algorithms with synchronized iterative training and prediction. This solution is implemented and evaluated on a software defined radio testbed. It results in performance of 50 dB in digital cancellation, which is close to the hardware limit and significantly outperformed available literature digital cancellation solutions. It also demonstrates stable performance across spectral band.
