In-band full-duplex wireless, i.e. simultaneous transmission and reception at the same frequency, promises to double channel capacity and has several other advantages. However, in-band full-duplex introduces strong self-interference (SI) that masks the signal to be received. Hence transceiver design becomes challenging. This presentation reviews the full-duplex transceiver problem and discusses some recently proposed innovations to address this problem.
