In this paper, we propose a novel spectrum sensing scheme based on the cyclostationarity of PU signals in high traffic environments. Specifically, we obtain a test statistic by applying an estimate of spectral autocoherence function of the PU signal to the generalized- likelihood ratio. From numerical results, it is confirmed that the proposed scheme provides a better spectrum sensing performance compared with the conventional spectrum sensing scheme based on the energy of the PU signals in high traffic environments. }, journal = {International Journal of Electrical and Computer Engineering}, volume = {7}, number = {9}, year = {2013}, pages = {1199 - 1202}, ee = {https://publications.waset.org/pdf/16679}, url = {https://publications.waset.org/vol/81}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 81, 2013}, }
