Implementation issues for optimized hard decision energy detector-based cooperative spectrum sensing
CogART '11: Proceedings of the 4th International Conference on Cognitive Radio and Advanced Spectrum ManagementArticle No.: 8, Pages 1–5https://doi.org/10.1145/2093256.2093264Recent studies in cooperative energy detection have focused on the optimization of the threshold value and fusion center voting rule in an effort to minimize the sensing error probability. However, such studies operate under the assumption that the ...

Minimizing the coarse-fine spectrum sensing time of cognitive radios with ideal secondary detectors subject to noise uncertainty: an analytical approach
CogART '11: Proceedings of the 4th International Conference on Cognitive Radio and Advanced Spectrum ManagementArticle No.: 1, Pages 1–5https://doi.org/10.1145/2093256.2093257In previous work a method was derived for generating estimates of design curves for Coarse-Fine spectrum sensing. One of the problems that the method had was it could not account for variations in noise power. If the noise was uncertain or not the same ...
