Furthermore, no research has treated the effect of correlated composite Rayleigh-lognormal fading, also known as Suzuki fading, in cognitive radio. This paper proposes a technique for reuse of shadowed CRs, discarded during the sensing phase, as amplified-and-forward (AF) diversity relays for other surviving CRs to mitigate the effects of such fading in reporting channels. A thorough analysis of and a closed-form expression for the outage probability of the resulting cooperative AF diversity network in correlated composite Rayleigh-lognormal fading channels are presented in this paper. In particular, an efficient solution to the “PDF of sum-of-powers” of correlated Suzuki-distributed random variables using moment generating function (MGF) is proposed. publisher: The Institute of Electronics, Information and Communication Engineers date: 2015 type: Article type: PeerReviewed format: application/pdf language: en identifier: https://eprints.uet.vnu.edu.vn/eprints/id/eprint/1691/1/e98-b_1_116.pdf identifier: Dinh, Thi Thai Mai and Nguyen, Quoc Tuan and Nguyen, Dinh Thong (2015) On the Reuse of Shadowed CRs as AF Diversity Relays in Cooperative Spectrum Sensing in Correlated Suzuki Fading Channels.
