Cooperative Spectrum Sensing Using Random Matrix Theory [PDF]
2008 3rd International Symposium on Wireless Pervasive Computing, 2008 In this paper, using tools from asymptotic random matrix theory, a new cooperative scheme for frequency band sensing is introduced for both AWGN and fading channels. Unlike previous works in the field, the new scheme does not require the knowledge of the

Cooperative Spectrum Sensing Schemes with the Interference Constraint in Cognitive Radio Networks [PDF]
Sensors, 2014 In this paper, we propose cooperative spectrum sensing schemes, called decode-and-forward cooperative spectrum sensing (DF-CSS) scheme and amplify-and-forward cooperative spectrum sensing (AF-CSS) scheme, in cognitive radio networks.

Convex Sensing-Reporting Optimization for Cooperative Spectrum Sensing [PDF]
IEEE Transactions on Wireless Communications, 2011 We consider the cooperative spectrum sensing problem in cognitive radio with energy detection. Secondary users with non-identical, independent sensing channels make 1-bit sensing decisions and report their decisions to the secondary base station over orthogonal fading channels. The base station acts as a fusion center by combining the decisions with OR-

Cooperative Spectrum Prediction-Driven Sensing for Energy Constrained Cognitive Radio Networks
IEEE Access, 2021 Spectrum prediction based sensing schemes minimize the overall energy consumption of the sensing module in cognitive radio networks (CRNs) by predicting the status of spectrum before performing actual physical sensing. But, the performance of independent
