摘要: In this paper, we first investigate and contrast the features of energy detection cyclostationary feature for spectrum sensing. Combining advantages both, propose an adaptive two-stage sensing scheme which performs using detector in cognitive dynamic access networks. Then decides whether or not to implement based on results stage. On premise meeting a given constraint probability false alarm, our proposed aim optimize detection. order obtain optimal thresholds, model is formulated as nonlinear optimization problem. Furthermore, performance speed also analyzed. The simulation show that improves compared with ones where only performed. DOI : http://dx.doi.org/10.11591/telkomnika.v12i5.4944
