A cognitive radio (CR) network is often described as a secondary network operating in a frequency band originally licensed/allocated to a primary network consisting of one or multi...
Abstract--In cognitive radio (CR) networks with multipleinput multiple-output (MIMO) links, secondary users (SUs) can exploit "spectrum holes" in the space domain to acce...
— The cognitive radio and cognitive wireless networks paradigms are interesting candidates for the next generation self-organizing and self-reconfigurable wireless networks. In ...
Cognitive radio (CR) emerges as a key technology to enhance spectrum efficiency and thus creates opportunistic transmissions over links. Supporting the routing function on top of n...
