Cooperative spectrum sensing using opportunistic amplify‐and‐forward relaying over Nakagami‐ m fading channels

Signal processing for cooperative cognitive radio networks

“…The effect of the duty cycle on the minimum total error rate is analyzed in Figure 4. 22. In a fixed total mean time (i.e., µ T = µ i + µ b ), as P b becomes low µ b decreases while µ i increases, which results in lower probabilities of H 11 and H 02 (higher probabilities of H 01 and H 12 ).…”

“…Many works have been published in the field of spectrum sensing under different conditions of the CRN in terms of primary and secondary networks' properties and the quality of sensing channel (the link between SU and PU). In a wireless environment the sensing channel can be treated as either additive white Gaussian noise (AWGN) [17,18] or faded (such as Rayleigh and Nakagami fading) [19][20][21][22][23][24][25].…”

“…In [22,40], the CSS was analyzed over Nakagami-m faded channels. Moreover, a great work has been done in [25], in which the faded sensing channel is modeled by the extended generalized-K (EGK), as a general distribution which can be simplified to the most well-known fading distributions (such as Nakagami-m, Rayleigh and Weibull).…”
