Learning-Based Spectrum Sensing for Cognitive Radio Systems by Yasmin Hassan, Mohamed El-Tarhuni, Khaled Assaleh

“…This paper presents a novel pattern recognition approach to spectrum sensing in collaborative cognitive radio systems. In the proposed scheme, discriminative features from the received signal are extracted at each node and used by a classifier at a central node to make a global decision about the availability of spectrum holes for use by the cognitive radio network. …”

The Information Theoretic Approach to Signal Anomaly Detection for Cognitive Radio by Mostafa Afgani, Sinan Sinanović, Harald Haas

“…Efficient utilisation and sharing of limited spectrum resources in an autonomous fashion is one of the primary goals of cognitive radio. However, decentralised spectrum sharing can lead to interference scenarios that must be detected and characterised to help achieve the other goal of cognitive radio—reliable service for the end user. …”
