Practical designs of wireless full-duplex are made feasible by reducing self-interference via active and passive methods. However, extending the range to long-range communication remains a challenge, primarily due to residual self-interference even after a combination of active cancellation and passive suppression methods is employed. In this paper, we study the factor that limits the amount of active cancellation in current designs of full-duplex. Through an experiment, we show that phase…

On the Impact of Phase Noise on Active Cancelation in Wireless Full-Duplex
The root cause of performance bottlenecks in current full-duplex systems is investigated and signal models for wideband and multiple-input-multiple-output (MIMO) full- DUplex systems are proposed, capturing all the salient design parameters, thus allowing future analytical development of advanced coding and signal design for full- duplex systems.
Analysis and reduction of the impact of thermal noise on the Full-Duplex OFDM radio
A little modification to the structure of data packet of IEEE 802.11g to reduce the impact of the thermal noise on the ASIC for Full-Duplex OFDM radio and co-simulation results show that the residual self-interference can be reduced to only 1.5dB higher than the receiver thermal noise.
Passive Self-Interference Suppression for Full-Duplex Infrastructure Nodes
These results suggest two design implications: (1) deployments of full-duplex infrastructure nodes should minimize near-antenna reflectors, and (2) active cancellation in concatenation with passive suppression should employ higher-order filters or per-subcarrier cancellation.
A Multi-Stage Self-Interference Canceller for Full-Duplex Wireless Communications
The proposed SI canceller consists of a two-stage passive reconstruction based analog cancellation which can suppress not only the strongest SI component but also multi-path SI components received within tens of nanoseconds, and a final stage of digital cancellation for suppressing the remaining SI components.
Self-interference cancellation with nonlinear distortion suppression for full-duplex systems
A self-interference cancellation scheme for full-duplex orthogonal frequency division multiplexing systems is proposed, which increases the amount of cancellable self- interference power by suppressing the distortion caused by the transmitter and receiver nonlinearities.
Effect of phase noise on digital self-interference cancellation in wireless full duplex
The theoretical analysis and simulations reveal that the digital SIC ability degrades with the increase of the ratio of the oscillator's 3dB coherence bandwidth to the signal bandwidth, which determines the upper bound of the digitalSIC ability.

A novel augmented nonlinear digital self-interference canceller is proposed that is able to model and hence suppress all the essential transmitter imperfections jointly and is verified and demonstrated by extensive waveform simulations.
Impacts of Phase Noise on Digital Self-Interference Cancellation in Full-Duplex Communications
Based on the obtained digital cancellation capability, the achievable rate region of a two-way FD OFDM system with phase noise is characterized and the maximum outer bound of the rate region is proved to exist for sufficiently large transmission power.
An Investigation Into Baseband Techniques for Single-Channel Full-Duplex Wireless Communication Systems
A two-stage iterative self-interference cancellation scheme based on the output signal of the power amplifier that substantially outperforms existing digital cancellation schemes for full-duplex wireless communication systems.
Analysis of Oscillator Phase-Noise Effects on Self-Interference Cancellation in Full-Duplex OFDM Radio Transceivers
The results show that phase noise has a severe effect on self-interference cancellation in both of the considered cases, and that by using the common oscillator in upconversion and downconversion results in clearly lower residual self- interference levels.


Experiment-Driven Characterization of Full-Duplex Wireless Systems
This work shows that the average amount of cancellation increases for active cancellation techniques as the received self-interference power increases, and shows that digital cancellation is more effective when applied selectively based on measured suppression values.

If the self-interference is cancelled in the analog domain before the interfering signal reaches the receiver front end, then the resulting full-duplex system can achieve rates higher than the rates achieved by a half-dulex system with identical analog resources.
