Shannon Theoretic Limits on Noisy Compressive Sampling
Mehmet Akçakaya, Vahid Tarokh
In this paper, we study the number of measurements required to recover a sparse signal in with non-zero coefficients from compressed samples in the presence of…
A Distributed Dynamic Frequency Allocation Algorithm
Behtash Babadi, Vahid Tarokh
We consider a network model where the nodes are grouped into a number of clusters and propose a distributed dynamic frequency allocation algorithm that achieves performance close t…
On the Degrees of Freedom in Cognitive Radio Channels
Natasha Devroye, Vahid Tarokh
After receiving useful peer comments, we would like to withdraw this paper.
Performance Bounds on Sparse Representations Using Redundant Frames
Mehmet Akçakaya, Vahid Tarokh
We consider approximations of signals by the elements of a frame in a complex vector space of dimension and formulate both the noiseless and the noisy sparse representation pro…
