Abstract
Ever-increasing use of wireless applications is exerting pressure on the limited, insufficient, and expensive licensed spectrum. Actually, because of allocation of fixed spectrum, more portion of spectrum is underutilized. Spectrum sensing can be used for the efficient and effective use of the radio spectrum. It detects the unused spectrum channels in cognitive radio network. In cognitive radio, spectrum sensing techniques such as energy detection, matched filter detection have been used. In this paper, receiver operating characteristics (ROC) of matched filter and energy detector are compared at −10 and −15 dB signal-to-noise Ratio (SNR) levels in fading wireless channels. From the results obtained it is found that matched filter system performed well over the ROC of energy detector at lower values of SNR.
