Abstract

This chapter overviews the state-of-the-art techniques for self-interference (SI) mitigation and cancellation within multi-antenna in-band full-duplex radio transceivers. Signal models taking into account the non-idealities of transceiver components are formulated, making it possible to devise digital nonlinear adaptive SI cancellation algorithms. The chapter presents major factors in the in-band full-duplex transceiver that need to be addressed in SI mitigation and cancellation. It reviews methods for improving the natural and hence passive isolation between the transmitter (TX) and the receiver (RX) through advanced antenna design. The chapter provides mathematical formulation of signals in multiple-antenna transceivers, including the effect of non-idealities of RF components. It derives advanced digital algorithms for SI mitigation and cancellation, making use of multiple antennas and the non-ideality models of the RF components. The chapter exemplifies the capability of the mentioned SI mitigation and cancellation techniques by integrating them and observing the residual SI level in a practical transceiver with off-the-shelf RF components.
