Techniques of self-interference incoherent digital holography

2015 IEEE 13th International Conference on Industrial Informatics (INDIN), 2015
We discuss and demonstrate our recent developments using self-interference incoherent digital holography to bridge the gap between indispensable incoherent imaging techniques and the advantages of three-dimensional holographic recording. We demonstrate the ability to record broadband sunlit photographic holograms, apply non-invasive three-dimensional ...

Filter Design for Self-Interference Cancellation

2020
Mitigation 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.

Applications of self-interference cancellation in 5G and beyond

IEEE Communications Magazine, 2014
Self-interference cancellation invalidates a long-held fundamental assumption in wireless network design that radios can only operate in half duplex mode on the same channel. Beyond enabling true in-band full duplex, which effectively doubles spectral efficiency, self-interference cancellation tremendously simplifies spectrum management.

Self-Interference Assessment and Mitigation in 3GPP IAB Deployments

ICC 2021 - IEEE International Conference on Communications, 2021
The high propagation losses and sensitivity to link blockage naturally require dense deployments of millimeter-wave (mmWave) 5G New Radio (NR) systems. One of the inherent challenges in these deployments is cost-efficient backhauling. Addressing this issue, 3GPP has recently proposed the concept of integrated access and backhaul (IAB) to reduce the ...

Biological applications of spectral self-interference

SPIE Proceedings, 2004
An original technique, Spectral Self-Interference Fluorescence Microscopy (SSFM), can determine the location of fluorescent markers above a reflecting surface with sub-nanometer precision. SSFM was used to resolve the position of a fluorescent marker bound to either the top or the bottom leaflet of a lipid bilayer -- the difference in distance is only ...

The performance of Bluetooth network with self interference

2002 3rd International Symposium on Electromagnetic Compatibility, 2003
Bluetooth network performance in the presence of self interference is evaluated by simulation. Self interference arises because different piconets' frequency hopping and clocks are asynchronous. The performance criteria used are FER (frame error rate) and throughput. The relation between performance and piconet number is studied by simulation.

Smart Self-interference Suppression by Exploiting a Nonlinearity

2013
A 1.8GHz RF amplifier implemented in 0.14um CMOS with frequency-independent blocker suppression is presented. The blocker suppression functionality is obtained by the adaptation of a nonlinear input–output transfer according to the blocker amplitude. Since superposition does not apply to nonlinear transfer functions, the behavior of such a transfer for

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

Electrochemiluminescence Self-Interference Spectroscopy with Vertical Nanoscale Resolution

Journal of the American Chemical Society, 2020
Here we report an electrochemiluminescence (ECL) self-interference spectroscopy technique (designated as ECLIS) with spatial resolution in the normal direction of the electrode surface. Self-interference principally originates from the superposition of ECL emitted directly by luminophores and that reflected from electrode surfaces, resulting in a ...

Study on the Properties of the SPPs Self-Interference

Advanced Materials Research, 2013
In this paper, surface plasmon polaritions (SPPs) induced by a tightly focused and radially polarized vortex beam on a planar metal/dielectric interface is simulated and the properties of the SPPs self-interference are studied. It is shown that utilizing vortex beam can avoid the influence of the central zero-order angular spectrum.
