Abstract

In this paper, we describe an advanced real-time cancellation architecture for efficient digital-domain suppression of self-interference in inband full-duplex devices. The digital canceller takes into account the nonlinear distortion produced by the transmitter power amplifier, and is thereby a robust solution for low-cost implementations. The developed real-time digital canceller implementation is then evaluated with actual RF measurements, where it is complemented with a real-time adaptive RF canceller. The obtained results show that the RF canceller and the developed digital canceller implementation can together cancel the residual self-interference below the receiver noise floor in real-time for a 20 MHz cancellation bandwidth.
