Multi-hop Cooperative Wireless Networks: Diversity Multiplexing Tradeoff and Optimal Code Design
In this paper, we consider single-source, single-sink (ss-ss) multi-hop relay networks, with slow-fading Rayleigh links and single-antenna relay nodes operating under the half-dupl...

On Optimal Cooperator Selection Policies for Multi-Hop Ad Hoc Networks
Abstract—In this paper we consider wireless cooperative multihop networks, where nodes that have decoded the message at the previous hop cooperate in the transmission toward the ...

Construction of New Delay-Tolerant Space-Time Codes
Perfect Space-Time Codes are optimal codes in their original construction for Multiple Input Multiple Output (MIMO) systems. Based on cyclic division algebras, they are full-rate,...
