Anti-Eavesdropping Space-Time Network Coding for Cooperative Communications

Network Coding for Cooperative Communications

In this paper, we propose network coding, as an efficient and low cost option for the implementation of blockMarkov coding for cooperative communications. Cooperative communications is a strategy where users, besides transmitting their own encoded information, also relay re-encoded versions of other users’ information to a common destination. Our work is motivated by the recent information-theo...

Cooperative space-time codes with network coding

Because of the gains like diversity, throughput, and the coverage extension provided by the multiple-input multipleout (MIMO) systems, it has been part of the various wireless communications standards. However, to reap the benefits offered by MIMO systems in size-constrained nodes, used in wireless communications, has been a challenging issue. To address this challenge, cooperative communicatio...

Space-time coding for broadband wireless communications

Distributed space-time coding for cooperative networks

In this report we show how proper cooperation among radio nodes may provide diversity gain, also for single antenna systems. We consider first the connectivity of a wireless network and show how it can benefit from cooperation. Then, we consider some specific forms of cooperations, based on distributed space-time coding, in both single and multi-user contexts. Finally, we pay a special attentio...
