Full-Duplex Self-Interference Cancellation Using Dual-Neurons Neural Networks

IEEE Communications Letters, 2022
In-band full-duplex (FD) technology has protruded as one of the most promising solutions for spectrum scarcity, by allowing users to transmit and receive simultaneously at the same center frequency.

Limiting Factors in Self-Interference Cancellation

2017
Various experimental results have stated that the self-interference (SI) in full-duplex communication can be mitigated to properly detect the intended signal. However, relatively little is known about the cancellation limits of these systems. A good SI-cancellation strategy passes first by a proper understanding of the nature of this SI. This is highly

A New Tuning Algorithm Based on Variable Step Approaching for RF Self-Interference Cancellation

IEEE Wireless Communications Letters
Radio frequency (RF) domain cancellation is a necessary process to mitigate self-interference (SI) for Full-Duplex (FD) wireless communication systems. Multi-taps RF canceller is designed for accurately reconstructing the multipath SI signals by deriving

Photonics-Assisted Ultrawideband RF Self-Interference Cancellation With Signal of Interest Recovery and Fiber Transmission

Journal of Lightwave Technology, 2022
Self-interference and chromatic dispersion are two main limiting factors that influence the recovery of the signal of interest (SOI) in in-band full-duplex (IBFD) radio-over-fiber (RoF) links.

Antennas and Radio Frequency Self-Interference Cancellation

2020
This chapter presents and reviews radio frequency (RF) transceiver architectures for in-band full-duplex, spanning both antenna techniques and RF cancellation loops. In the antenna domain, isolation can be achieved using separate transmit and receive antennas, exploiting propagation loss for transmit-to-receive isolation, or through more complicated ...

Design of a passive self-interference cancellation network with high cancellation ratio

2013 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference, 2013
A passive self-interference cancellation network (SICN) is proposed in this paper. The network is composed of three directional couplers and microstrip delay lines. By adjusting the coupling factor of the two parallel coupled line directional couplers and the length of the delay lines, the proposed SICN is able to produce an optimized reference signal ...

Influence of Full-Duplex Self-Interference Channel Measurement on Self-Interference Cancellation Capacity

2018 8th International Conference on Electronics Information and Emergency Communication (ICEIEC), 2018
In full-duplex system, the key research of analog self-interference cancellation are self-interference channel and reconstruction circuit for self-interference suppression. In this paper, we measure the self-interference channel using the vector-based channel response measurement method, and analyze the effects of tap delay, tap interval, tap number ...
