DMT of Multi-hop Cooperative Networks - Part II: Half-Duplex Networks with Full-Duplex Performance
K. Sreeram, S. Birenjith, P. Vijay Kumar
We consider single-source single-sink (ss-ss) multi-hop relay networks, with slow-fading links and single-antenna half-duplex relay nodes. In a companion paper, we established some…
DMT of Multi-hop Cooperative Networks - Part I: Basic Results
K. Sreeram, S. Birenjith, P. Vijay Kumar
In this two-part paper, the DMT of cooperative multi-hop networks is examined. The focus is on single-source single-sink (ss-ss) multi-hop relay networks having slow-fading links a…
Diversity Multiplexing Tradeoff of Asynchronous Cooperative Relay Networks
R. N. Krishnakumar, N. Naveen, P. Vijay Kumar
The assumption of nodes in a cooperative communication relay network operating in synchronous fashion is often unrealistic. In the present paper, we consider two different models o…
Diversity and Degrees of Freedom of Cooperative Wireless Networks
K. Sreeram, S. Birenjith, P. Vijay Kumar
Wireless fading networks with multiple antennas are typically studied information-theoretically from two different perspectives - the outage characterization and the ergodic capaci…
Multi-hop Cooperative Wireless Networks: Diversity Multiplexing Tradeoff and Optimal Code Design
K. Sreeram, S. Birenjith, P. Vijay Kumar
We consider single-source single-sink (ss-ss) multi-hop networks, with slow-fading links and single-antenna half-duplex relays. We identify two families of networks that are multi-…
Approximately-Universal Space-Time Codes for the Parallel, Multi-Block and Cooperative-Dynamic-Decode-and-Forward Channels
Petros Elia, P. Vijay Kumar
Explicit codes are constructed that achieve the diversity-multiplexing gain tradeoff of the cooperative-relay channel under the dynamic decode-and-forward protocol for any network…
