An Exact Characterization of Greedy Structures
We present exact characterizations of structures on which the greedy algorithm produces optimal solutions. Our characterization, which we call matroid embeddings, complete the par...

Optimized Paraunitary Filter Banks for Time-Frequency Channel Diagonalization
We adopt the concept of channel diagonalization to time-frequency signal expansions obtained by DFT filter banks. As a generalization of the frequency domain channel representatio...
