| Abstract |
: |
Cognitive Radio is an emerging technology which avoids the congestion in wireless communication by exploiting unused radio spectrum . The Spectrum sensing plays a fundamental requirement of CR which finds an unused free spectrum and detects the licensed user transmissions.energy detection constitutes a preferred approach for cognitive rdio spectrum sensing due to its simple applicability. In this paper Wiener khinchin theorem ,QAM techniques are used for the energy detection |
