Sparse non-negative super-resolution — simplified and stabilised
We consider the problem of non-negative super-resolution, which concerns reconstructing a non-negative signal x = ki=1 aiδti from m samples of its convolution with a window function φ(s−t), of the form y(sj ) = ki=1 aiφ(sj −ti)+δj , where δj indicates an inexactness in the sample value. We first sho...
