Unitary space-time constellations based on quasi-orthogonal sequences
In this paper, we propose a novel class of unitary space-time constellations based on quaternary quasi-orthogonal sequences (QOSs), minimizing the maximum correlation between the s...

Separating sources from sequentially acquired mixtures of heart signals
In this paper, we consider the problem of separating a set of independent components when only one movable sensor is available to record the mixtures. We propose to exploit the qu...
