Residual self-interference after cancellation in full-duplex systems
2014 IEEE International Conference on Communications (ICC), 2014We investigate the signal-to-residual-interference ratio (SIR out ) in a full-duplex transceiver with analog self-interference cancellation in consideration of three major sources of imperfection: (i) self-interference channel estimation error, (ii) quantization error in the receiver analog-to-digital converter (ADC), and (iii) quantization error in ...

Digital self-interference cancellation for Full-Duplex MIMO systems
2015 International Wireless Communications and Mobile Computing Conference (IWCMC), 2015An attractive hybrid method of mitigating the effects of the residual self-interference imposed by the signal propagation and analog/digital circuit non-idealities for Full-Duplex (FD) point-to-point multiple-input multiple-output (MIMO) systems is proposed. Furthermore, the effect of channel estimation errors on system performance is considered.

Self-Interference Cancellation for Full-Duplex in Spatial-Polarized Domain
2018 15th International Symposium on Wireless Communication Systems (ISWCS), 2018Self-interference cancellation is critical in full duplex networks and its mitigation capability is limited mainly due to the phase noise caused by imperfect local oscillators. In this paper, a novel self-interference cancellation scheme in spatial-polarized domain is analyzed for full duplex systems.

A numerical investigation of all-analog radio self-interference cancellation
2014 IEEE 15th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2014Radio self-interference cancellation (SIC) is the fundamental enabler for full-duplex radios. While SIC methods based on baseband digital signal processing and/or beamforming are inadequate, an all-analog method is useful to drastically reduce the self-interference as the first stage of SIC. However, all-analog radio SIC has so far received very little

Wideband self-interference cancellation for better spectrum use
2016 IEEE 17th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM), 2016A large enough separation in the frequency domain between signals going in opposite directions is instrumental to facilitate the implementation of transceivers able to isolate the receiver from the high power transmitted signal. A more flexible allocation of spectrum requires the application of interference cancellation countermeasures.

Efficient and fair MAC for wireless networks with self-interference cancellation
2011 International Symposium of Modeling and Optimization of Mobile, Ad Hoc, and Wireless Networks, 2011Recent advances in PHY layer design demonstrated efficient self-interference cancellation and full-duplex in a single band. Building a MAC that exploits self-interference cancellation is a challenging task. Links can be scheduled concurrently, but only if they either (i) don't interfere or (ii) allow for self-interference cancellation. Two issues arise:

The projection-based self-interference cancellation scheme in the polarization domain
2014 International Symposium on Wireless Personal Multimedia Communications (WPMC), 2014In this paper, we propose a self-interference cancellation scheme for the full duplex communication in the polarization domain. The proposed scheme cancels self-interference first by orthogonal projection to the null space of the self-interference before the analog to digital converter (ADC).

Self-Interference-Cancellation in Full-Duplex Systems
2017This chapter provides a brief overview of several important concepts related to SI-cancellation techniques to form a solid background for the following chapters. We first discuss the nature of the self-interference (SI) channel which leads to the use of the analog RF cancellation stage and the digital cancellation stage.

Analysis of DAC Impact on Digital-controlled Self-interference Cancellation
2019 Joint International Symposium on Electromagnetic Compatibility, Sapporo and Asia-Pacific International Symposium on Electromagnetic Compatibility (EMC Sapporo/APEMC), 2019Adaptive interference cancellation is an effective approach to enable full-duplex wireless communication in the multi-antenna co-site shipboard environments. Regarding the new digital-controlled cancellation implementation, the paper presents the system model, deduces the quantitative analytical expressions of interference suppression with and without ...

Active Signal Injection for Self-Interference-Cancellation
2017A common problem in full-duplex operation is the existence of a large self-interference (SI) at the receiver input, which prevents the proper detection of the intended signal. This chapter presents a new active signal injection (ASI) approach for full-duplex multiple-input multiple-output (MIMO) OFDM systems to reduce the SI prior to the receiver low ...
