Map-aided Dead-reckoning --- A Study on Locational Privacy in Insurance Telematics
Johan Wahlström, Isaac Skog, João G. P. Rodrigues +2
We present a particle-based framework for estimating the position of a vehicle using map information and measurements of speed. Two measurement functions are considered. The first…
The -model for Random Graphs --- Regression, Cramér-Rao Bounds, and Hypothesis Testing
Johan Wahlström, Isaac Skog, Patricio S. La Rosa +2
We develop a maximum-likelihood based method for regression in a setting where the dependent variable is a random graph and covariates are available on a graph-level. The model gen…
Smartphone-based Vehicle Telematics - A Ten-Year Anniversary
Johan Wahlström, Isaac Skog, Peter Händel
Just like it has irrevocably reshaped social life, the fast growth of smartphone ownership is now beginning to revolutionize the driving experience and change how we think about au…
Hilbert Transform, Analytic Signal, and Modulation Analysis for Graph Signal Processing
Arun Venkitaraman, Saikat Chatterjee, Peter Händel
We propose Hilbert transform (HT) and analytic signal (AS) construction for signals over graphs. This is motivated by the popularity of HT, AS, and modulation analysis in conventio…
Scalable and Passive Wireless Network Clock Synchronization
Dave Zachariah, Satyam Dwivedi, Peter Händel +1
Clock synchronization is ubiquitous in wireless systems for communication, sensing and control. In this paper we design a scalable system in which an indefinite number of passively…
Compressive Sampling Based UWB TOA Estimator
Vijaya Yajnanarayana, Peter Handel
This paper proposes two compressive sampling based time of arrival (TOA) estimation algorithms using a sub-Nyquist rate receiver. We also describe a novel compressive sampling dict…
