Power adaptation for cognitive radio systems under an average sinr loss constraint in the absence of path loss information
(Kluwer Academic Publishers, 2014)
An upper bound is derived on the capacity of a cognitive radio system by considering the effects of path loss and log-normal shadowing simultaneously for a single-cell network. Assuming that the cognitive radio is informed ...
Spectrum sensing via restricted neyman-pearson approach in the presence of non-Gaussian noise
In this paper, spectrum sensing in cognitive radio systems is studied for non-Gaussian channels in the presence of prior distribution uncertainty. In most practical cases, some amount of prior information about signals of ...
Optimal detector randomization in cognitive radio systems in the presence of imperfect sensing decisions
In this study, optimal detector randomization is developed for secondary users in a cognitive radio system in the presence of imperfect spectrum sensing decisions. It is shown that the minimum average probability of error ...
