A Case For Amplify-Forward Relaying in the Block-Fading Multi-Access Channel
Deqiang Chen, Kambiz Azarian, J. Nicholas Laneman
This paper demonstrates the significant gains that multi-access users can achieve from sharing a single amplify-forward relay in slow fading environments. The proposed protocol, na…
Cooperative Lattice Coding and Decoding
Arul Murugan, Kambiz Azarian, Hesham El Gamal
A novel lattice coding framework is proposed for outage-limited cooperative channels. This framework provides practical implementations for the optimal cooperation protocols propos…
On the Optimality of the ARQ-DDF Protocol
Kambiz Azarian, Hesham El Gamal, Philip Schniter
The performance of the automatic repeat request-dynamic decode and forward (ARQ-DDF) cooperation protocol is analyzed in two distinct scenarios. The first scenario is the multiple…
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…
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…
