Abstract
The success of the CR systems which are based on energy detection-based scheme depends primarily on the selection of threshold \( (\lambda ) \). This \( \lambda \) is selected either by using the CDR principle in which the probability of detection \( P_{\text{d}} \) is kept constant or by using the CFAR principle in which the probability of false alarm \( P_{\text{fa}} \) is kept constant. The approach used in this paper is based on the power received from primary transmitter. To properly utilize the licensed spectrum, schemes used are namely: CDR under opportunistic spectrum access scheme (OSA) and spectrum sharing with sensing scheme. Compared to the approach where the CDR principle is used blindly the throughput under the proposed approach experiences a significant gain.
