摘要：

A secondary fading multiple access channel (S-FMAC) with two transmitters, having random available bandwidth taking values 0 or 1 and one coherent receiver knowing random and independent channel coefficients, has been studied before. In this paper, we investigate the wiretap version of S-FMAC as a secondary multiple access wiretap channel (S-MAC-WT) over similar Rayleigh/ Rayleigh and dissimilar Rayleigh/Nakagami fading, and having briefly reviewed the point to point version, we obtain closed-form expressions for the secrecy rate region and the corresponding outage probability. To validate the theoretical results, secrecy outage probability for sum-rate of S-FMAC-WT is numerically computed. © 2020 Elsevier B.V.
