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 ...
Optimal channel switching for average capacity maximization
Optimal channel switching is proposed for average capacity maximization in the presence of average and peak power constraints. A necessary and sufficient condition is derived in order to determine when the proposed optimal ...
