Sparse non-negative super-resolution -- simplified and stabilised

Armin Eftekhari, Jared Tanner, Andrew Thompson +2

The convolution of a discrete measure, $x={\sum }_{i=1}^k{a}_i{\delta }_{t_i}$, with a local window function, $\varphi (s-t)$, is a common model for a measurement device whose resolution is substantia…
