Decentralized support detection of multiple measurement vectors with joint sparsity
This paper considers the problem of finding sparse solutions from multiple measurement vectors (MMVs) with joint sparsity. The solutions share the same sparsity structure, and th...

Emitter Localization and Visualization (ELVIS): A Backward Ray Tracing Algorithm for Locating Emitters
— We present ELVIS, a new approach for localizing a first responder (e.g., firefighter) inside a building. We assume that the first responder emits RF energy, which undergoes...
