Abstract

Cognitive radio (CR) has been fronted as technology for spectrum sharing. For a CR to work efficiently and effectively, the secondary user (SU) should without any reasonable doubt detect the presence or the absence of the primary user (PU). Therefore, spectrum sensing is core to the performance of cognitive radio networks and it is shown in this paper that deploying multiple input multiple output (MIMO) at the SU, improves the performance. In addition, this paper deploys multi-slots and cooperative spectrum sensing to enhance detection in CR networks. Results show that the probability of detection increases while the probability of false alarm decreases for a MIMO implementation. An overall performance improvement in the network throughput is realized by increasing the number of antennas, sensing time slots and the number of users.
