Synchronous deautoconvolution algorithm for discrete-time positive signals via I-divergence approximation

Lorenzo Finesso, Peter Spreij

We pose the problem of the optimal approximation of a given nonnegative signal $y_t$ with the scalar autoconvolution $(x\ast x{)}_t$ of a nonnegative signal $x_t$, where $x_t$ and $y_t$…
