On the Secrecy Capacity of Fading Channels
TL;DR: The positive impact of fading on the secrecy capacity is revealed and the critical role of rate adaptation, based on the main channel CSI, in facilitating secure communications over slow fading channels is established.

On the Secrecy Capacity of Fading Channels
TL;DR: In this article, the authors considered the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper and characterized the secrecy capacity of such a system under the assumption of asymptotically long coherence intervals.

On the Throughput-Delay Tradeoff in Cellular Multicast
TL;DR: A cross layer design approach for analyzing the throughput-delay tradeoff of the multicast channel in a single cell system and the proposed cooperative multicast strategy is shown to simultaneously achieve the optimal scaling laws of both throughput and delay.

On the throughput-delay tradeoff in cellular multicast

TL;DR: In this article, the authors adopt a cross layer design approach for analyzing the throughput-delay tradeoff of the multicast channel in a single cell system and show that a static scheduling policy achieves the optimal scaling law of the throughput at the expense of a delay that increases exponentially with the number of users.
