“…In order to face these difficulties [10] a distributed and cooperative approach to the spectrum sensing phase can be deployed [10]. In particular, different approaches can be defined [10] in accordance with the amount of data exchanged among secondary users.…”

“…Although a high number of different spectrum sensing techniques have been proposed in the open literature, e.g. energy detection, matched filters or feature detection [7], [8], many issues still persist, to find out a fast and trustworthy spectrum sensing algorithm remains a challenging task [2], [9] in the CR context.…”

“…Moreover, in real environments, the signal received by the secondary terminals is often corrupted by channel distortions. In particular, path loss, multipath fading and shadowing effects can cause a significant signal impairment [7], [9]. Such variation in the power of the received signal due to, as an example, a sudden deep fade, lead to a probable undesirable primary user missed detection [9] and, as a consequence, to a misleading identification of a spectrum hole [7], [8].…”
