2021 IEEE Radio Frequency Integrated Circuits Symposium (RFIC), 2021
Self-interference (SI) mitigation is critical for full-duplex and frequency-domain duplex systems. Canceller noise and linearity limits the SI power that can be tolerated at RX input. A dual-path SI cancellation scheme is presented where the noise and distortion from the canceller are addressed through a differential noise-cancelling path. The proposed

End-to-End Learned Self-Interference Cancellation
2022 56th Asilomar Conference on Signals, Systems, and Computers, 2022Full-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.

Antennas and Radio Frequency Self-Interference Cancellation
2020This 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 ...

Micro-Acoustic Quad Circulator with Self-Interference Cancellation
2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS), 2020In this paper, a micro-acoustic RF circulator with novel “quad” configuration is reported. Four micro-acoustic filters are periodically modulated by RF switches to break the reciprocity. The use of high-Q micro-acoustic filters significantly reduces the modulation frequency (14 MHz) compared to previous demonstrations based on transmission lines (e.g.,

A Multichannel Self-Interference Cancellation Prototyping System
2019 IEEE 2nd 5G World Forum (5GWF), 2019This 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 ...

Maximum Likelihood Self-Interference Cancellation
2017In this chapter, we propose a maximum likelihood (ML) approach to jointly estimate the self-interference and the intended channels. We perfectly exploit the known transmitted symbols from its own transceiver and both the known pilot and unknown data symbols from the other intended transceiver.

Filter Design for Self-Interference Cancellation
2020Mitigation of self-interference is the prime challenge in making full-duplex technology feasible in wireless communications. In this chapter, we first present system model of a wireless communication link including a source, full-duplex transceiver, and destination, and discuss different approaches and assumptions when building the signal model.
