Abstract |
Cognitive radio is a new paradigm in wireless communication to improve the spectrum utilization. Spectrum sensing is a very important function of cognitive radio to find the vacant spectrum hole. First, we have studied a heuristic approach for spectrum sensing. This is a technique which adapts the sensing procedure by varying the sensing window size and adapts according to the SNR received by the detector and the activity of PU. Now, in this paper, instead of conventional energy detector, we have used an improved energy detector. Numerical results have demonstrated that the use of improved energy detector in the adaptive sensing procedure has improved the probability of detection significantly. Index terms - Cognitive Radio, Spectrum Sensing, Window Size, Spectrum Hole Utilization. | |||||||||
