Software Defined Radio for GNSS Radio Frequency Interference Localization

open access: yesSensors, 2023
The use of radio direction finding techniques in order to identify and reject harmful interference has been a topic of discussion both past and present for signals in the GNSS bands.

Radio Interferometric Angle of Arrival Estimation [PDF]

open access: yes, 2010
Several localization algorithms exist for wireless sensor networks that use angle of arrival measurements to estimate node position. However, there are limited options for actually obtaining the angle of arrival using resource-constrained devices. In this paper, we describe a radio interferometric technique for determining bearings from an anchor node ...

Gaussian Channel Model for Mobile Multipath Environment

open access: yesEURASIP Journal on Advances in Signal Processing, 2004
A model of an angle-spread source is described, termed the “Gaussian channel model” (GCM). This model is used to represent signals transmitted between a user equipment and a cellular base station.

Tensor-Based Angle Estimation Approach for Strictly Noncircular Sources with Unknown Mutual Coupling in Bistatic MIMO Radar

open access: yesSensors, 2018
In the paper, the estimation of joint direction-of-departure (DOD) and direction-of-arrival (DOA) for strictly noncircular targets in multiple-input multiple-output (MIMO) radar with unknown mutual coupling is considered, and a tensor-based angle ...

Power Scalable Angle of Arrival Estimation Using Pilot Design With Orthogonal Subsequences

open access: yesIEEE Open Journal of the Communications Society, 2021
Energy efficient array processing is critical to implement feasible solutions for directional communication in a mmWave channel. MmWave channels are highly susceptible to blockage and require frequent angle of arrival (AoA) estimation.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Direction of Arrival Estimation in Low-Grazing Angle: A Partial Spatial-Differencing Approach

open access: yesIEEE Access, 2017
This paper addresses a partial spatial-differencing (PSD) approach for the direction of arrival estimation in a low-grazing angle (LGA) condition. By dividing the sample covariance matrix into several column subvectors, we first form the corresponding ...
