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…
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…
