Vertex-disjoint Cycle Cover for graph signal processing
Raghavendra Singh
Eigenvectors of the Laplacian of a cycle graph exhibit the sinusoidal characteristics of the standard DFT basis, and signals defined on such graphs are amenable to linear shift inv…
On the Public Communication Needed to Achieve SK Capacity in the Multiterminal Source Model
Manuj Mukherjee, Navin Kashyap, Yogesh Sankarasubramaniam
The focus of this paper is on the public communication required for generating a maximal-rate secret key (SK) within the multiterminal source model of Csisz{á}r and Narayan. Buildi…
Recovery of a Sparse Integer Solution to an Underdetermined System of Linear Equations
T. S. Jayram, Soumitra Pal, Vijay Arya
We consider a system of m linear equations in n variables Ax=b where A is a given m x n matrix and b is a given m-vector known to be equal to Ax' for some unknown solution x' that…
Optimal Function Computation in Directed and Undirected Graphs
Hemant Kowshik, P. R. Kumar
We consider the problem of information aggregation in sensor networks, where one is interested in computing a function of the sensor measurements. We allow for block processing and…
Joint Source-Channel Coding on a Multiple Access Channel with Side Information
R. Rajesh, Vinod Sharma, V. K. Varshenya
We consider the problem of transmission of several distributed correlated sources over a multiple access channel (MAC) with side information at the sources and the decoder. Source-…
