N2 - Cognitive radio is a promising technology to overcome the insufficiency of available communication spectrums. In the cognitive radio system, many important issues exist. Spectrum sensing is one of the important issues, which has been studied throughout recently. In this paper, we propose a new distributed spectrum sensing scheme which considers the difference of sensing capabilities among cognitive terminals. By using our proposed scheme, we can effectively measure the sensing capability of a cognitive terminal and optimize the performance of the spectrum sensing by differentiating the number of spectrum sensing that each cognitive terminal performs. Through performance analysis and numerical results, we show that our proposed scheme can achieve desired performance in view of the probability of false alarm and the probability of miss detection compared to a conventional scheme.
