A Wavelet Filter Bank Which Minimizes a Novel Translation Invariant Discrete Uncertainty Measure
We develop a novel measure of joint time-frequency localization applicable to equivalence classes of finite-length discrete signals, which are of increasing importance in modern ...

Notes on averaging over acyclic digraphs and discrete coverage control
In this paper we study averaging algorithms and coverage control laws in a unified light. First, we characterize the convergence properties of averaging algorithms over acyclic di...
