Collaborative relays achieve the benefits of spatial diversity without requiring physical antenna arrays at end devices. While many studies have demonstrated its effectiveness in a...
— We consider a wireless multiuser network where a number of source/destination pairs communicate concurrently over the same physical channel. A set of amplify-and-forward relay ...
—In this paper, we propose a generalized cooperative signal transmission model for wireless networks. In this model, the source, the destination, and an arbitrary number of relay...
Relay-based cooperative communications can achieve spatial diversity gains, enhance coverage and potentially increase capacity. If considered for large networks, traditional relayi...
Abstract--Cooperative transmission is an emerging communication technique that takes advantage of the broadcast nature of wireless channels. However, due to low spectral efficiency...
