Passive Localization Through Channel Estimation of On-the-Air LTE Signals

open access: yesIEEE Access, 2019
Wireless communication signal is a kind of coherent illuminator, and it can shed light on surrounding environments. The mobile terminal receives the signal and estimate the propagation channel, and can sense the moving objects passively. The localization

Ant Colony Pheromone Mechanism-Based Passive Localization Using UAV Swarm

open access: yesRemote Sensing, 2022
The problem of passive localization using an unmanned aerial vehicle (UAV) swarm is studied. For multi-UAV localization systems with limited communication and observation range, the challenge is how to obtain accurate target state consistency estimates ...

From Cutting Planes Algorithms to Compression Schemes and Active Learning [PDF]

open access: yes, 2015
Cutting-plane methods are well-studied localization(and optimization) algorithms. We show that they provide a natural framework to perform machinelearning ---and not just to solve optimization problems posed by machinelearning--- in addition to their ...

Leveraging Smart Lights for Passive Localization

open access: yes2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS), 2018
Localization based on visible light is gaining significant attention. But most existing studies rely on a key requirement: the object of interest needs to carry an optical receiver (camera or photodiode). We remove this requirement and investigate the possibility of achieving accurate localization in a passive manner, that is, without requiring objects

Interplay between localization and absorption in disordered waveguides [PDF]

open access: yes, 2013
This work presents results of ab-initio simulations of continuous wave transport in disordered absorbing waveguides. Wave interference effects cause deviations from diffusive picture of wave transport and make the diffusion coefficient position- and ...

High Resolution Direct Detection and Position Determination of Sources With Intermittent Emission

open access: yesIEEE Access, 2019
This paper presents our research findings on the direct detection and position determination (DDPD) problem, which is to estimate the positions and the total number of multiple sources with intermittent emission, using the received signals intercepted by

Separating Predicted and Perceived Sensory Consequences of Motor Learning. [PDF]

open access: yesPLoS ONE, 2016
During motor adaptation the discrepancy between predicted and actually perceived sensory feedback is thought to be minimized, but it can be difficult to measure predictions of the sensory consequences of actions.

Wave propagation through a coherently amplifying random medium [PDF]

open access: yes, 1997
We report a detailed and systematic numerical study of wave propagation through a coherently amplifying random one-dimensional medium. The coherent amplification is modeled by introducing a uniform imaginary part in the site energies of the disordered ...

Sound Source Localization in a Multipath Environment Using Convolutional Neural Networks

open access: yes, 2017
The propagation of sound in a shallow water environment is characterized by boundary reflections from the sea surface and sea floor. These reflections result in multiple (indirect) sound propagation paths, which can degrade the performance of passive ...
