Phase retrieval, Norm retrieval, Frame vectors, Unitary systems Wandering subspacesAbstract
In a separable Hilbert space , we introduce phase and norm retrievable frame generators for a unitary system and show that phase retrievable and norm retrievable vectors and subspaces can be obtained with a unitary system structure. We give the conditions under which a complete wandering subspace for a unitary system can generate vectors and subspaces that do phase retrieval and norm retrieval in .
