Novel Cancellation Techniques and Throughput Analysis for 6G Full-Duplex Wireless System

Space: Science & Technology
Recent researches show that it is possible to achieve full-duplex system if the self-interference signal could be cancelled completely for 6G research. The majority of the overall self-interference cancellation is contributed by passive cancellation. The

RF Self-Interference Cancellation for Radio-Over-Fiber Link Based on Dual Phase Modulation in Sagnac Loop

IEEE Photonics Journal, 2021
The in-band full-duplex (IBFD) systems can send and receive data simultaneously in the same frequency band. Although the electromagnetic interference among RF channels can be released using radio over fiber (RoF) links, the receiving antenna is ...

Active Self-Interference Cancellation Mechanism for Full-Duplex Wireless Transceivers [PDF]

Proceedings of the 9th International Conference on Cognitive Radio Oriented Wireless Networks, 2014
This paper investigates active cancellation techniques for a Full-Duplex transceiver. An auxiliary transmit chain is employed to create the cancellation signal, which is then injected at the receiver RF front-end by using a microstrip cou-pler. Two methods are proposed to calculate the self-interference cancellation signal.

Full-Duplex 60GHz Transceiver with Digital Self-Interference Cancellation

Electronics, 2023
This paper presents the design and measurement of an IEEE 802.11ad standard compatible RF transceiver for 60GHz wireless communication system. In addition to the traditional half-duplex (HD) mode, this work supports full-duplex (FD) operation to deliver better channel utilization and faster response time for the system.

Radio self-interference cancellation by transmit beamforming, all-analog cancellation and blind digital tuning [PDF]

Signal Processing, 2015
Radio self-interference cancellation has been a technological challenge for more than a century while it is the most critical enabler for full-duplex radios. The eventual success of radio self-interference cancellation may well depend on not only improved hardware technology but also innovative signal processing schemes. In this paper, we present a few
