MmWave Full-Duplex Wireless Communication: TX-RX Self-Interference Reduction Through Passive Cancellation Techniques

Abstract

Full-duplex (FD) wireless has recently emerged as a new technology that enables a wireless device to transmit and receive at the same time and on the same frequency band. Recent works have shown that it is possible to significantly reduce the self-interference (SI) and build small-antenna low-frequency (sub-6 GHz) FD radios.
