Blind self-interference cancellation for full-duplex relays
2014 48th Asilomar Conference on Signals, Systems and Computers, 2014Full-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

Enhancement of lateral resolution in confocal self-interference microscopy
Optics Letters, 2003We describe confocal self-interference microscopy with enhanced lateral resolution. A uniaxial anisotropic crystal is used to cause interference between two linearly polarized beams that are reflected from the same pointlike object in the focal plane of the objective lens. Theory and the optimal design that maximizes the sensitivity of the interference

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.

MIMO On-Frequency Repeater with Self-Interference Cancellation and Mitigation
VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009In 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

Limiting Factors in Self-Interference Cancellation
2017Various experimental results have stated that the self-interference (SI) in full-duplex communication can be mitigated to properly detect the intended signal. However, relatively little is known about the cancellation limits of these systems. A good SI-cancellation strategy passes first by a proper understanding of the nature of this SI. This is highly

Computational Imaging with Self-Interference
Interferometry records the relative phase between incident light and a reference beam. Since phase encodes the path information of the scene, it can be applied to tasks including 3D imaging or undoing effects of scattering. However, a reference beam requires a controllable external light source, which is not always available in many applications.openaire +1 more source
Self-Interference Lloyd's Fiber Interferometer
CLEO:2011 - Laser Applications to Photonic Applications, 2011We proposed an ultracompact, simple and robust in reflection-type of self-interference Lloyd's fiber interferometer based on a diffused-core fiber endface with Sn-overlay. Interference fringes are observed experimentally and investigated for the first time.

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.
