Wavelet denoising in cooperative and NonCooperative spectrum sensing
ICT 2013, 2013Cognitive Radio has become an effective solution for the scarcity and the inefficient use of the spectrum. The performance of the cognitive radio (CR) system depends however on how well it can maximize the usage of the free bands without causing interference to primary users.

Quantized cooperative spectrum sensing for Cognitive Radio
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013Cognitive Radio (CR) is proposed to maximize spectrum utilization. When the licensed user is not using the spectrum, CR will then use it to communicate among each other. Hence, spectrum sensing, a procedure to observe primary user's existence, is important to CR.

Privacy-preserving aggregation for cooperative spectrum sensing
Journal of Network and Computer Applications, 2019Abstract Cognitive radio technology has been proposed as a promising way to alleviate spectrum scarcity. In cognitive radio networks, cooperative spectrum sensing is an effective approach to improve spectrum-estimation accuracy. In this approach, a fusion center (FC) outsources sensing tasks to secondary users (SUs), and aggregates sensing reports ...

An Improved Double-Threshold Cooperative Spectrum Sensing
2011Cognitive Radio is becoming a hot research topic in wireless communication field now, in which the spectrum sensing is one of the most critical technologies. In the double-threshold cooperative spectrum sensing, the fusion center collects the local decisions and observational values of the secondary users, and then makes the final decision to determine

Robust DNN-Enabled Cooperative Spectrum Sensing
2024 International Conference on Software, Telecommunications and Computer Networks (SoftCOM)In this contribution, we investigate cooperative spectrum sensing in cognitive radio networks using a deep neural network approach. Our proposed architecture leverages the strengths of both a one dimentional convolutional neural network and a bidirectional long short-term memory network.
