Abstract: A constrained joint dictionary learning (CJDL) algorithm for highâprecision channel representation in massive multiple input multiple output (MIMO) satellite systems is proposed. Furthermore, taking into account the angular reciprocity of massive MIMO satellite systems, joint… read more here.

DOI: 10.1117/1.jmi.5.3.034001
Abstract: Abstract. Magnetic resonance imaging (MRI) provides a number of advantages over computed tomography (CT) for radiation therapy treatment planning; however, MRI lacks the key electron density information necessary for accurate dose calculation. We propose a… read more here.
