Sensors – Special Issue on Full-Duplex Wireless Communications

To meet the rising demand for high-speed data services, wireless networks must exploit the available frequency spectrum more efficiently. One key limit to spectrum utilization efficiency involves the current practice of half-duplex communication, in which a node either transmits or receives a signal in a single-channel usage. This separation prevents self-interference, which has frequently been seen as an insurmountable technical problem. Promoted by the popularity of small-cell wireless systems, recent works have provided experimental evidence and methodologies for full-duplex communication, in which a node transmits and receives signals at the same time and on the same frequency band. Full-duplex communications have the potential to improve the attainable spectral efficiency and throughput and reduce latency.

This Special Issue will provide a synthesized source of recent research results and to serve as a springboard for future work in Full-Duplex Wireless Communications. The possible topics include, but are not limited to the following:

• Advanced self-interference cancellation techniques for full-duplex
• Advanced antenna and transceiver designs for full-duplex
• Full-duplex reconfigurable intelligent (meta)surfaces
• Full-duplex techniques with wireless power and energy harvesting
• Full-duplex for simultaneous communication and sensing
• Full-duplex millimeter-wave/THz systems
• Multiple input multiple output full-duplex transceiver design
• Performance analysis of full-duplex transceivers, systems, and networks
• Physical layer security and full-duplex techniques
• Resource allocation and user scheduling in full-duplex networks
• Stochastic geometry for full-duplex systems
• Experimental evaluation of full-duplex transceivers and networks
