Simple and practical algorithm for sparse Fourier transform
We consider the sparse Fourier transform problem: given a complex vector x of length n, and a parameter k, estimate the k largest (in magnitude) coefficients of the Fourier transf...

Sparse Coding of Natural Images Using an Overcomplete Set of Limited Capacity Units
It has been suggested that the primary goal of the sensory system is to represent input in such a way as to reduce the high degree of redundancy. Given a noisy neural representati...

Optimality of Diagonalization of Multicarrier Multi-Hop Linear Non-Regenerative MIMO Relays
Abstract—In this paper, a multicarrier multi-hop multipleinput multiple-output (MIMO) relay system is investigated. A linear non-regenerative strategy is applied at each relay no...
