Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

In order to mitigate the shortage of wireless spectrum, the appealing concepts of cooperative
communication techniques and cognitive radio (CR) networks have been combined for the …

We propose novel cooperative spectrum sensing (CSS) algorithms for cognitive radio (CR)
networks based on machine learning techniques which are used for pattern classification. In …

Spectrum sensing is a key function of cognitive radio to prevent the harmful interference with
licensed users and identify the available spectrum for improving the spectrum's utilization …

Cognitive radio is an exciting emerging technology that has the potential of dealing with the
stringent requirement and scarcity of the radio spectrum. Such revolutionary and …

We consider cooperative spectrum sensing in which multiple cognitive radios collaboratively
detect the spectrum holes through energy detection and investigate the optimality of …

Detection performance of an energy detector used for cooperative spectrum sensing in a
cognitive radio network is investigated over channels with both multipath fading and …

This paper focuses on the performance analysis and comparison of hard decision (HD) and
soft decision (SD) based approaches for cooperative spectrum sensing in the presence of …

Performance of cooperative spectrum sensing with multiple antennas at each cognitive radio
(CR) is discussed in this paper. The CRs utilize selection combining of the decision statistics …
