MIMO On-Frequency Repeater with Self-Interference Cancellation and Mitigation

VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
In this paper, we consider the idea of a MIMO on- frequency repeater (OFR), with end-to-end MIMO channel rank preservation, MIMO aware repeater output-to-input self- interference cancellation, and a new repeater output-to-input beamforming based interference mitigation method for MIMO signals. The latter is used to increase the repeater output-to-input

Fluid Antenna System-Assisted Self-Interference Cancellation for In-Band Full Duplex Communications

IEEE Transactions on Wireless Communications
In-band full-duplex (IBFD) systems are expected to double the spectral efficiency compared to half-duplex systems, provided that loopback self-interference (SI) can be effectively suppressed.

Blind self-interference cancellation for full-duplex relays

2014 48th Asilomar Conference on Signals, Systems and Computers, 2014
Full-duplex relays increase the spectral efficiency and diversity, especially for the amplify and forward mode. However, transmission and reception in the same frequency band produce coupling between the transmitted and received signals that needs to be reduced. The cyclic prefix introduced in modern modulations produces a periodic autocorrelation that

An In-Band Full-Duplex Prototype With Joint Self-Interference Cancellation in Antenna, Analog, and Digital Domains

IEEE transactions on microwave theory and techniques
In-band full-duplex (IBFD) technology has been extensively researched over the last decade, and numerous techniques have been proposed to cancel self-interference (SI) caused by the simultaneously transmitted local in-band signal.

Digital Domain Self-Interference Cancellation Based on Modified Variable Step-Size LMS Algorithm

2023 5th International Conference on Communications, Information System and Computer Engineering (CISCE), 2023
As one of the key technologies of 6G, co-time co-frequency full duplex (CCFD) technology can more effectively utilize the spectrum and hardware resources of the radio system. However, the biggest challenge of this technology is how to cancel out the self-

Photonic-Assisted Adaptive Multipath Self-Interference Cancellation Using Deep Reinforcement Learning

Journal of Lightwave Technology, 2023
Multipath self-interference (MSI) between the transmitter and receiver is an inevitable problem in realistic in-band full-duplex (IBFD) transmissions. Due to the dynamic and intricate MSI channels, it is crucial for the MSI cancellation system to quickly
