Multidimensional orthogonal matching pursuit: theory and application to high accuracy joint localization and communication at mmWave
Joan Palacios, Nuria González-Prelcic, Cristian Rusu
Greedy approaches in general, and orthogonal matching pursuit in particular, are the most commonly used sparse recovery techniques in a wide range of applications. The complexity o…
Low complexity joint position and channel estimation at millimeter wave based on multidimensional orthogonal matching pursuit
Joan Palacios, Nuria González-Prelcic, Cristian Rusu
Compressive approaches provide a means of effective channel high resolution channel estimates in millimeter wave MIMO systems, despite the use of analog and hybrid architectures. S…
A Note on Shift Retrieval Problems
Cristian Rusu
In this note, we discuss the shift retrieval problems, both classical and compressed, and provide connections between them using circulant matrices. We review the properties of cir…
Algorithms for the Construction of Incoherent Frames Under Various Design Constraints
Cristian Rusu, Nuria Gonzalez-Prelcic, Robert W. Heath
Unit norm finite frames are generalizations of orthonormal bases with many applications in signal processing. An important property of a frame is its coherence, a measure of how cl…
