Optical Self-Interference Cancellation With Frequency Down-Conversion Based on Cascade Modulator
IEEE Photonics Journal, 2020 A novel approach to simultaneous radiofrequency self-interference cancellation (SIC) and frequency down-conversion in a unified system is proposed and demonstrated experimentally based on cascade Mach–Zehnder modulators (MZM). The local oscillator

Extending 5G TDD Coverage With XDD: Cross Division Duplex
IEEE Access, 2021 An advanced duplex scheme called cross-division duplex (XDD) is proposed to enhance uplink (UL) coverage in time division duplex (TDD) carriers by utilizing self-interference cancellation (SIC) capability at a base station.

Linear Precoders for Non-Regenerative Asymmetric Two-way Relaying in Cellular Systems [PDF]
, 2013 Two-way relaying (TWR) reduces the spectral-efficiency loss caused in conventional half-duplex relaying. TWR is possible when two nodes exchange data simultaneously through a relay.
