The problem of underutilization of spectrum may be solved by allowing the Secondary Users (SUs) to use the spectrum allocated to the Primary Users (PUs) (license holder of a spectrum band) when they are not using it, without causing any harmful interference to the PUs. Cognitive Radio (CR) technology promises to solve the problem of spectrum underutilization and spectrum crowding. The cognitive users employ their cognitive abilities, to adaptively change the radio parameters as per the radio environment, to communicate, without harming the primary users.
