Abstract

In this paper, we provide capacity and outage probability analysis with different sensing results for three different transmission scenarios in the cognitive radio networks, i.e., overlay, underlay, and cooperative transmission of secondary users (SUs) relaying for primary users(PUs) (CToSP) according to [1]. Numerical results show that CToSP model achieves better performance under given situations, and different sensing results impact much.
