Hierarchical MTC User Activity Detection and Channel Estimation with Unknown Spatial Covariance

no code implementations16 Oct 2023 Hamza Djelouat, Mikko J. Sillanpää, Markus Leinonen, Markku Juntti

To solve the JUICE problem, we first leverage the concept of strong priors and propose a hierarchical-sparsity-inducing spike-and-slab prior to model the structured sparse activity pattern.
