Abstract

Spectrum sensing is the distinct feature of cognitive radio technology that makes it significant different from other wireless technologies developed so far. This feature embed cognition to the handheld device embeds Spectrum sensing gives an idea of detecting the presence of the incumbent users in a licensed spectrum. In most of the previous works, researchers either have taken fixed threshold or adapted it based on signal to noise ratio at receiver end. In this paper, we have used channel information rather than signal to noise ratio to decide threshold of an energy detector and shown that our proposed technique improves detection probability and reduce false alarm probability over state of art techniques available so far.
