Explicit Full-Spark Gabor Windows with Quantitative Phase Retrieval
Dongwei Li
We construct explicit algebraic finite Gabor windows that are simultaneously full spark and phase retrievable, with quantitative control of the self-ambiguity function. In every cy…

On weaving frames in Hilbert spaces
Dongwei Li
In this paper, we obtain some new properties of weaving frames and present some conditions under which a family of frames is woven in Hilbert spaces. Some characterizations of weav…

Splitting of operator for frame inequalities in Hilbert spaces
Dongwei Li
In this paper, we obtain a new type of inequalities for frames, which are parametrized by a parameter λ\in R . By suitable choices of λ, one obtains the previous results as special…
