Popis:	Algorithm enhancements are proposed for single-shot phase retrieval to reduce loss from ill-conditioning. The approach is based on prior observations, improved diffraction pattern up-sampling, and updated filters. High-quality super-resolved reconstructions are demonstrated in simulation. acceptedVersion Non
