In this letter, the optimal channel switching and randomization problem is formulated its solution characterized for flat-fading Gaussian noise channels with aim of outage capacity maximization under average power probability constraints. For single user scenario, it proved that can always be realized by performing one following strategies: (1) Transmission over a no randomization. (2) Channel ...
