Continuous Approach to Phase (Norm) Retrieval Frames
Ramin Farshchian, Rajab Ali Kamyabi-Gol, Fahimeh Arabyani-Neyshaburi +1
This paper investigates the properties of continuous frames, with a particular focus on phase retrieval and norm retrieval in the context of Hilbert spaces. We introduce the concep…
Characterization of (weak) phase retrieval dual frames
Fahimeh Arabyani-Neyshaburi, Ali Akbar Arefijamaal, Rajab Ali Kamyabi-Gol
Recovering a signal up to a unimodular constant from the magnitudes of linear measurements has been popular and well studied in recent years. However, numerous unsolved problems re…
A New Look at Optimal Dual Problem Related to Fusion Frames
Fahimeh Arabyani-Neyshaburi, Ali Akbar Arefijamaal
The purpose of this work is to examine the structure of optimal dual fusion frames and get more exibility in the use of dual fusion frames for erasures of subspaces. We deal with o…
Matrix Methods for Perfect Signal Recovery Underlying Range Space of Operators
Fahimeh Arabyani Neyshaburi, Rajab Ali Kamyabi-Gol
The most important purpose of this article is to investigate perfect reconstruction underlying range space of operators in finite dimensional Hilbert spaces by matrix methods. To t…
