An Improved Double-Threshold Cooperative Spectrum Sensing

2011
Cognitive 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

Reinforcement Learning-Based Cooperative Spectrum Sensing

2019
In cognitive radio (CR) networks, the detection result of a single user is susceptible due to shadowing and multipath fading. In order to find an idle channel, the secondary user (SU) should detect channels in sequence, while the sequential detection may cause excessive overhead and access delay.

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.
