Abstract:

Cognitive radio is the most promising and reliable emerging technology which can utilize the scarce radio spectrum efficiently. In this technology the secondary (unlicensed) users need to find idle channels by spectrum sensing for their transmission. Spectrum sensing may be single user or cooperative. However cooperative spectrum sensing is considered better. In this paper simple overview on different spectrum sensing techniques in cognitive radio is given. Apart from that the various challenging issues in spectrum sensing are outlined.

Keywords:

cognitive radio, dynamic spectrum access, primary user, secondary user, spectrum sensing.
