Sampling and Reconstruction of Signals on Product Graphs
Guillermo Ortiz-Jiménez, Mario Coutino, Sundeep Prabhakar Chepuri +1
In this paper, we consider the problem of subsampling and reconstruction of signals that reside on the vertices of a product graph, such as sensor network time series, genomic sign…
Sparse Sampling for Inverse Problems with Tensors
Guillermo Ortiz-Jiménez, Mario Coutino, Sundeep Prabhakar Chepuri +1
We consider the problem of designing sparse sampling strategies for multidomain signals, which can be represented using tensors that admit a known multilinear decomposition. We lev…
Sparse Antenna and Pulse Placement for Colocated MIMO Radar
Ehsan Tohidi, Mario Coutino, Sundeep Prabhakar Chepuri +3
Multiple input multiple output (MIMO) radar is known for its superiority over conventional radar due to its antenna and waveform diversity. Although higher angular resolution, impr…
