Secret Sharing Schemes for Very Dense Graphs
A secret-sharing scheme realizes a graph if every two vertices connected by an edge can reconstruct the secret while every independent set in the graph does not get any informatio...

Degrees of Freedom and Sum Rate Maximization for Two Mutually Interfering Broadcast Channels
— In this paper, we derive a precise expression of spatial degrees of freedom (DOF) for two mutually interfering broadcast channels (IFBC) as a function of arbitrary numbers of t...
