— We consider a cognitive radio system like the future 802.22 networks where license-exempt service providers (SPs) will share a fixed spectrum in a non-interference basis to ea...
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...
- Current wireless systems are called vendor-central systems because, users should subscribe to a service provider (vendor) and receive the service through the spectrum assigned to...
