Cognitive Radio Based Multi-User Resource Allocation in Mobile Ad Hoc Networks Using Multi-Carrier CDMA Modulation

Cyclostationary Feature Detection in Cognitive Radio using Different Modulation Schemes

QoS optimization for multimedia transmission over cognitive radio networks using multicarrier modulation

Spectrum sensing is the basic and essential mechanisms of Cognitive Radio (CR) to find the unused spectrum. This paper presents an overview of CR architecture, discusses the haracteristics and benefits of a CR. Energy detectionbased spectrum sensing
