Self-interference cancellation in full-duplex wireless with IQ imbalance

Physical Communication, 2016
To achieve full-duplex wireless communication, the most essential issue is to eliminate in-band self-interference caused by simultaneous transmission and reception. In this paper, we investigate the impact of transmitter IQ imbalance on digital signal processing (DSP)-assisted analog self-interference cancellation, where two transmitters are used for ...

Analysis of utilizing lossless networks for self-interference cancellation purpose

2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018
In this paper, novel self-interference cancellation technique is proposed. The technique addresses in particularly the transceivers where dedicated-transmit-and-receive antenna configurations are embraced. The technique, moreover, relies on a lossless decoupling network, which interconnects the transceiver's chains to the antenna elements.

Optimized Sequences for Nonlinearity Estimation and Self-Interference Cancellation

IEEE Transactions on Communications
In wireless communication systems, nonlinearity is the root cause of many undesired effects. In order to compensate these effects, the nonlinearity must be estimated accurately.

Lightweight Digital Self-Interference Cancellation

2024 IEEE/CIC International Conference on Communications in China (ICCC)
As has been known, co-frequency co-time full-duplex transmission can double the bandwidth efficiency of half-duplex by overlapping the transmitted and received signals in frequency and time domains. While, for approaching the theoretical gain of doubling

All-Digital Self-Interference Cancellation Technique for Full-Duplex Systems [PDF]

IEEE Transactions on Wireless Communications, 2015
Full-duplex systems are expected to double the spectral efficiency compared to conventional half-duplex systems if the self-interference signal can be significantly mitigated.

A Noise-Cancelling Self-Interference Canceller with +7 dBm Self-Interference Power Handling in 0.18μ m CMOS

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

Photonics-Assisted Simultaneous RF Channelization and Self-Interference Cancellation

Journal of Lightwave Technology, 2023
Both RF channelization and self-interference cancellation are urgently required for modern in-band full-duplex systems. A photonics-assisted RF receiver for simultaneous wideband channelization and self-interference cancellation is proposed and ...
