Abstract
Cognitive radio is widely expected to be the upcoming research topic in wireless communications sector. Detecting the presence of primary users in a licensed spectrum is achieved through the technique called spectrum sensing. In this paper spectrum two types of spectrum sensing techniques namely energy detection and matched filter techniques are reviewed.
