Non-negativity constraints in the one-dimensional discrete-time phase retrieval problem
Non-negativity constraints in the one-dimensional discrete-time phase retrieval problem
Phase retrieval problems occur in a wide range of applications in physics and engineering such as crystallography, astronomy and laser optics. Common to all of them is the recovery of an unknown signal from the intensity of its Fourier transform. Because of the well-known ambiguousness of these problems, the determination …
