Utilization of Noise-Only Samples in Array Processing With Prior Knowledge
Dave Zachariah, Magnus Jansson, Mats Bengtsson
For array processing, we consider the problem of estimating signals of interest, and their directions of arrival (DOA), in unknown colored noise fields. We develop an estimator tha…
Line Spectrum Estimation with Probabilistic Priors
Dave Zachariah, Petter Wirfält, Magnus Jansson +1
For line spectrum estimation, we derive the maximum a posteriori probability estimator where prior knowledge of frequencies is modeled probabilistically. Since the spectrum is peri…
Self-Localization of Asynchronous Wireless Nodes With Parameter Uncertainties
Dave Zachariah, Alessio De Angelis, Satyam Dwivedi +1
We investigate a wireless network localization scenario in which the need for synchronized nodes is avoided. It consists of a set of fixed anchor nodes transmitting according to a…
Cooperative localization by dual foot-mounted inertial sensors and inter-agent ranging
John-Olof Nilsson, Dave Zachariah, Isaac Skog +1
The implementation challenges of cooperative localization by dual foot-mounted inertial sensors and inter-agent ranging are discussed and work on the subject is reviewed. System ar…
Conservation laws, financial entropy and the Eurozone crisis
Paul Cockshott, David Zachariah
The report attempts of apply econophysics concepts to the Eurozone crisis. It starts by examining the idea of conservation laws as applied to market economies. It formulates a meas…
