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…

Estimation for the Linear Model with Uncertain Covariance Matrices

Dave Zachariah, Nafiseh Shariati, Mats Bengtsson +2

We derive a maximum a posteriori estimator for the linear observation model, where the signal and noise covariance matrices are both uncertain. The uncertainties are treated probab…

Training Sequence Design for MIMO Channels: An Application-Oriented Approach

Dimitrios Katselis, Cristian R. Rojas, Mats Bengtsson +5

In this paper, the problem of training optimization for estimating a multiple-input multiple-output (MIMO) flat fading channel in the presence of spatially and temporally correlate…
