Let $f(t)$ be an exponential sum and let ESPIRA-II, MPM, and ESPRIT denote the corresponding parameter-estimation methods applied to equidistant, possibly noisy samples of $f$. Sta…

Let a frame have $M$ vectors in an $N$-dimensional signal space, so that its redundancy is $M/N$. The mean-square error (MSE) of a consistent estimate is evaluated for a fixed sign…

Consider a scalar Gaussian system or a linear mixing system with a scalar or discrete channel, where the input ${\bf x}$ is sparse Gaussian or mixture Gaussian. Let…
