摘要

Abstract

The performance bound of cognitive radio systems is analyzed. We use opportunistic spectrum efficiency (OSE) as the performance metric, and point out that the maximum achievable OSE can be used to evaluate the maximum value that the introduction of secondary users can add to the conventional wireless systems. Based on assumptions of the PU's traffic model and some reasonable approximations, the expression of OSE is obtained and the maximum achievable OSE is derived by solving an optimization problem. The results are verified by computer simulation.
