A Novel Technique for Spectrum Sensing in Cognitive Radio Networks

Shailly Rastogi, Abhinav Bhargava

Abstract :

 In this paper detailed review of Spectrum shortage and the ineffective use of the electromagnetic spectrum motivated the development of Cognitive Radio (CR), which aims to make bigger the spectral efficiency, with opportunistic access to the obtainable frequency bands. Energy Detection (ED) is the majority adopted spectrum sensing technique for cognitive radio applications due to its simplicity. However, fading special, effects are usually basic or discarded when evaluating, the energy detector performance in spectrum sensing. Study with different possible configurations available to reconcile these quality issues. These configurations, have been illustrious on special parameters, like energy detection, false alarm, probabilities of detection. This paper proposes a novel technique to reduce false alarm and the interference for Cognitive Radio. In this technique detected signal pass through double square energy detector before measures the received energy in a selected time interval from t₁ to t₂, and match, the acquired measurement with a predetermined threshold energy level. This technique is called double square energy detection (DSED).This is one of the strong candidates technique for Future wire-less communication.
