The Water-Filling Game in Fading Multiple Access Channels
Lifeng Lai, Hesham El Gamal
We adopt a game theoretic approach for the design and analysis of distributed resource allocation algorithms in fading multiple access channels. The users are assumed to be selfish…
The Throughput-Reliability Tradeoff in MIMO Channels
Kambiz Azarian, Hesham El Gamal
In this paper, an outage limited MIMO channel is considered. We build on Zheng and Tse's elegant formulation of the diversity-multiplexing tradeoff to develop a better understandin…
The Three Node Wireless Network: Achievable Rates and Cooperation Strategies
Lifeng Lai, Ke Liu, Hesham El Gamal
We consider a wireless network composed of three nodes and limited by the half-duplex and total power constraints. This formulation encompasses many of the special cases studied in…
A Unified Framework for Tree Search Decoding : Rediscovering the Sequential Decoder
Arul D. Murugan, Hesham El Gamal, Mohamed Oussama Damen +1
We consider receiver design for coded transmission over linear Gaussian channels. We restrict ourselves to the class of lattice codes and formulate the joint detection and decoding…
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…
On the Achievable Diversity-Multiplexing Tradeoffs in Half-Duplex Cooperative Channels
Kambiz Azarian, Hesham El Gamal, Philip Schniter
In this paper, we propose novel cooperative transmission protocols for delay limited coherent fading channels consisting of N (half-duplex and single-antenna) partners and one cell…
