Learning Connectivity and Higher-order Interactions in Radial Distribution Grids
Qiuling Yang, Mario Coutino, Gang Wang +2
To perform any meaningful optimization task, distribution grid operators need to know the topology of their grids. Although power grid topology identification and verification has…
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…
Joint Detection and Localization of an Unknown Number of Sources Using Algebraic Structure of the Noise Subspace
Matthew W. Morency, Sergiy A. Vorobyov, Geert Leus
Source localization and spectral estimation are among the most fundamental problems in statistical and array signal processing. Methods which rely on the orthogonality of the signa…
Eigendecomposition-Based Partial FFT Demodulation for Differential OFDM in Underwater Acoustic Communications
Jing Han, Lingling Zhang, Qunfei Zhang +1
Differential orthogonal frequency division multiplexing (OFDM) is practically attractive for underwater acoustic communications since it has the potential to obviate channel estima…
The Dual Graph Shift Operator: Identifying the Support of the Frequency Domain
Geert Leus, Santiago Segarra, Alejandro Ribeiro +1
Contemporary data is often supported by an irregular structure, which can be conveniently captured by a graph. Accounting for this graph support is crucial to analyze the data, lea…
Consistent Sensor, Relay, and Link Selection in Wireless Sensor Networks
Rocio Arroyo-Valles, Andrea Simonetto, Geert Leus
In wireless sensor networks, where energy is scarce, it is inefficient to have all nodes active because they consume a non-negligible amount of battery. In this paper we consider t…
