ARQ Diversity in Fading Random Access Channels
Young-Han Nam, Praveen Kumar Gopala, Hesham El Gamal
A cross-layer optimization approach is adopted for the design of symmetric random access wireless systems. Instead of the traditional collision model, a more realistic physical lay…
On the Secrecy Capacity of Fading Channels
Praveen Kumar Gopala, Lifeng Lai, Hesham El Gamal
We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of…
On the Throughput-Delay Tradeoff in Cellular Multicast
Praveen Kumar Gopala, Hesham El Gamal
In this paper, we adopt a cross layer design approach for analyzing the throughput-delay tradeoff of the multicast channel in a single cell system. To illustrate the main ideas, we…
