In this paper, we present three embedding schemes for extensions of least significant bit overwriting to both of the two lowest bit planes in digital images. Our approaches are in...

We explore the capacity and generalized degrees of freedom of the 2-user Gaussian X channel, i.e. a generalization of the 2-user interference channel where there is an independent...

The capacity of a time-varying block-memoryless channel in which the transmitter and the receiver have access to (possibly different) noisy causal channel side information (CSI) i...

Discrete-time Rayleigh fading single-input single-output (SISO) and multiple-input multipleoutput (MIMO) channels are considered, with no channel state information at the transmit...

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...
