A Multichannel Self-Interference Cancellation Prototyping System

2019 IEEE 2nd 5G World Forum (5GWF), 2019
This paper presents the design and implementation of a multichannel self-interference cancellation system. The proposed design achieves self-interference cancellation via sequential transmit and receive beamforming. The prototype experiments prove that this system not only can suppress the self-interference to the receiver's noise floor over a wide ...

End-to-End Learned Self-Interference Cancellation

2022 56th Asilomar Conference on Signals, Systems, and Computers, 2022
Full-duplex communications systems can transmit and received information at the same time and on the same frequency band. However, they require strong self-interference (SI) cancellation. While a part of this SI cancellation is carried out in the analog domain, in most cases digital SI cancelation is required as well.

A Fiber-Transmission-Assisted Fast Digital Self-Interference Cancellation for Overcoming Multipath Effect and Nonlinear Distortion

Journal of Lightwave Technology, 2023
Self-interference (SI) influenced the recovery of the signal of interest (SOI) in In Band Full Duplex (IBFD) radio-over-fiber (ROF) links. The multipath effect and nonlinear distortion aggravate the difficulty of the SI signal elimination.

Neural Network Aided Digital Self-Interference Cancellation for Full-Duplex Communication Over Time-Varying Channels

IEEE Transactions on Vehicular Technology, 2022
In-band full duplex communication requires precise self-interference cancellation (SIC) to successfully decode the received desired signal. The existing neural network (NN) based SIC scheme uses offline trained NN to estimate the non-linear component of ...
