Robust Optimal Power Distribution for Hyperthermia Cancer Treatment
Nafiseh Shariati, Dave Zachariah, Johan Karlsson +1
We consider an optimization problem for spatial power distribution generated by an array of transmitting elements. Using ultrasound hyperthermia cancer treatment as a motivating ex…
Online Hyperparameter-Free Sparse Estimation Method
Dave Zachariah, Petre Stoica
In this paper we derive an online estimator for sparse parameter vectors which, unlike the LASSO approach, does not require the tuning of any hyperparameters. The algorithm is base…
Cramer-Rao bound analog of Bayes rule
Dave Zachariah, Petre Stoica
In this lecture note, we show a general property of the Cramer-Rao bound (CRB) that quantifies the interdependencies between the parameters in a vector. The presented result is val…
Joint Ranging and Clock Parameter Estimation by Wireless Round Trip Time Measurements
Satyam Dwivedi, Alessio De Angelis, Dave Zachariah +1
In this paper we develop a new technique for estimating fine clock errors and range between two nodes simultaneously by two-way time-of-arrival measurements us- ing impulse-radio u…
