Necessary and Sufficient Conditions for Sparsity Pattern Recovery

he paper considers the problem of detecting the sparsity pattern of a k -sparse vector in BBR n from m random noisy measurements. A new necessary condition on the number of measurements for asymptotically reliable detection with maximum-likelihood (ML) estimation and Gaussian measurement matrices is...
