LMMSE turbo equalization based on factor graphs
Abstract--In this paper, a vector-form factor graph representation is derived for intersymbol interference (ISI) channels. The resultant graphs have a tree-structure that avoids th...

New Constructive Approach to Covert Channel Modeling and Channel Capacity Estimation
In this paper, we examine general mechanisms that a covert channel may exploit and derive new minimum requirements for setting up a covert channel. We also propose a new classifica...
