Broadcast Channels With Privacy Leakage Constraints [PDF]
IEEE Transactions on Information Theory, 2017 The broadcast channel (BC) with one common and two private messages with leakage constraints is studied, where leakage rate refers to the normalized mutual information between a message and a channel symbol string. Each private message is destined for a different user and the leakage rate to the other receiver must satisfy a constraint.

Code design for MIMO broadcast channels [PDF]
IEEE Transactions on Communications, 2006 Recent information-theoretic results show the optimality of dirty-paper coding (DPC) in achieving the full capacity region of the Gaussian multiple-input multiple-output (MIMO) broadcast channel (BC). This paper presents a DPC based code design for BCs.

The State-Dependent Semideterministic Broadcast Channel [PDF]
IEEE Transactions on Information Theory, 2012 We derive the capacity region of the state-dependent semideterministic broadcast channel with noncausal state-information at the transmitter. One of the two outputs of this channel is a deterministic function of the channel input and the channel state, and the state is assumed to be known noncausally to the transmitter but not to the receivers. We show

Quantum Cloning, Eavesdropping and Bell's inequality [PDF]
, 1996 We analyze various eavesdropping strategies on a quantum cryptographic channel. We present the optimal strategy for an eavesdropper restricted to a two-dimensional probe, interacting on-line with each transmitted signal.
