Distributed MIMO for Cooperative Cognitive Radio Networks
Vinayak Nagpal and Borivoje Nikolic
Collaborative cognitive radio networks can achieve higher performances by utilizing the spatial dimension efficiently . The importance of the spatial dimension has increased further in light of recent results , which have shown that the total capacity of wireless ad hoc dense networks can scale linearly with the number of nodes using intelligent node-cooperation and distributed MIMO. Realizing a practical wireless network that uses spatial diversity through either distributed MIMO or distributed beam-forming poses several challenges, especially those of synchronizing the nodes. We are working towards understanding these challenges and finding ways to address them.
