Virtual MIMO network a physical wireless analysis
By analogy with an approach widely used in physics, we consider a discrete set of base stations (BS) as a continuum of transmitters. This model allows us to establish a simple clos...

Joint rate and power allocation for cognitive radios in dynamic spectrum access environment
Abstract--We investigate the dynamic spectrum sharing problem among primary and secondary users in a cognitive radio network. We consider the scenario where primary users exhibit o...

Optimal Spectrum Sharing in MIMO Cognitive Radio Networks via Semidefinite Programming
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...
