خلاصه مقاله:
In cognitive radio, each secondary user can individually use one of the signal detection techniques to decide whether the primary user is present or not. However, the hidden primary users' problem due to deep fading or shadowing dramatically affects the reliability and accuracy of the local sensing results. In other words, misdetection is highly probable due to fading and shadowing. In order to overcome this problem and enhance the detection performance, cooperative spectrum sensing has been proposed. In a cooperative approach, a number of secondary users experiencing different degrees of fading collaborate to improve the reliability and accuracy of their detection performance; of course at the cost of complexity and latency.
