In this paper, a reliable spectrum sensing (SS) scheme using dual detectors for IEEE 802.22 WRAN has been presented. In dual or double detectors, first one detector is energy detector (ED) with fixed threshold (FT), while second one is ED with adaptive double threshold (ADT). Numerical results shows that proposed reliable scheme improves detection performance and outperforms the cyclostationary based sensing method and adaptive SS by 12.9% and 15% at -8 dB signal-to-noise ratio (SNR), respectively. It also shows that the proposed scheme takes smaller detection time period than cyclostationary detection and adaptive SS scheme in the order of 5 ms and 0.8 ms at -20 dB SNR, respectively. Moreover, the scheme analyzes in conjunction with cooperative spectrum sensing (CSS) where each CRs work together in order to take final or global decision. It is observed that the proposed sensing scheme with CSS achieves spectrum detection performance in the order of 0.9 for SNR value of as low as -17.5 dB when numbers of CRs are ten. |
