Cooperative MAC for Rate Adaptive Randomized Distributed Space-Time Coding
—In a distributed wireless network, it is possible to employ several relays and mimic a multiple antenna transmission system. In this paper we propose a MAC layer solution that a...

Coding Strategies for Noise-free Relay Cascades with Half-Duplex Constraint
Abstract--Two types of noise-free relay cascades are investigated. Networks where a source communicates with a distant receiver via a cascade of half-duplex constrained relays, and...
