On the capacity of partially cognitive radios [PDF]
2009 IEEE International Symposium on Information Theory, 2009 This paper considers the problem of cognitive radios with partial-message information. Here, an interference channel setting is considered where one transmitter (the "cognitive" one) knows the message of the other ("legitimate" user) partially. An outer bound on the capacity region of this channel is found for the "weak" interference case (where the ...

A KNN Learning Algorithm for Collusion-Resistant Spectrum Auction in Small Cell Networks
IEEE Access, 2018 Existing spectrum auction algorithms rarely consider the collusion-resistant, which decreases the spectrum allocation efficiency. In this paper, we propose a collusion-resistant spectrum auction algorithm based on K-Nearest Neighbor (KNN) learning in ...

2012 9th International Conference on Communications (COMM), 2012 Cognitive Radio Networks (CRNs) are emerging as a solution to increase the spectrum utilization by using unused or less used spectrum in radio environments. The basic idea is to allow unlicensed users access to licensed spectrum, under the condition that the interference perceived by the licensed users is minimal.

2020 2nd Al-Noor International Conference for Science and Technology (NICST), 2020 Day by day, there is increasing demand for high data rates it causes lack of radio spectrum for the new emerging technologies in the area of wireless communications. So, it is, must use spectrum efficiently, i.e. proper spectrum management. Spectrum management is responsible for the spectrum deficiency.

Eigenvalue Based Detection by Combining Eigenvector-Correlated Signal in Low SNR Environment
IET Signal ProcessingEigenvalue detection is extensively utilized in numerous applications, including spectrum sensing in cognitive radio. However, the characteristics of the Tracy–Widom (TW2) distribution and its lack of accurate close-form expression limit the detection ...
