Abstract
In cognitive radio (CR) systems, the secondary user (SU) performs the spectrum sensing to determine the presence of the primary user (PU) on the PU's frequency band. In practical cases, the PU would arrive and depart randomly in the sensing duration of the SU, which is referred to as the high traffic circumstance. In this paper, we propose a cyclostationarity-based spectrum sensing scheme for CR systems in high traffic circumstances. From numerical results, it is confirmed that the proposed scheme outperforms both the energy detector proposed for high traffic circumstances and the conventional cyclostationarity-based spectrum sensing scheme.
