… Spectrum sensing is one of the most essential components of cognitive radio. In the following
we will present some topics in spectrum sensing for cognitive radio, that have been of great …

… tion, we define three classes of spectrum sensing schemes for cognitive radio networks
based on their keenness towards opportunistic spectrum usage: conservative, aggressive, and …

and interference protection is the key priority for the primary network. Thus, instead of sensing …

… sensing approaches can be classified as blind and knowledge aided approaches. This tutorial
summarizes blind spectrum … for an interweave cognitive radio network model. The tutorial …

… cognitive radio operation is the requirement that the radio is able to sense the environment
over huge swaths of spectrum and adapt to it since the radio does not have primary rights to …
