International audienceCognitive radio has been claimed to be a hopeful solu-tion to the existing conflicts between spectrum demand growth and spectrum underutilization. The basic underlying idea of cognitive radio is to allow unlicensed users to access in an oppor-tunistic and non-interfering manner some licensed bands tempo-rarily unoccupied by licensed users. The cognitive radio concept relies on two basic premises: the current spectrum underutiliza-tion, which has been demonstrated in some spectrum measure-ments campaigns, and the ability of unlicensed users to effectively detect and identify the presence of different licensed technologies in order not to cause harmful interference. In this context, this paper reports the joint work on t...
