Joint Detection of Cyclostationary and Energy in Cognitive Radio
Spectrum sensing is one of the most important technologies in the implementation of cognitive radio system using dynamic spectrum resource management. Since the performance of the widely used energy detector based approach will experience a significant loss under a small noise fluctuation, especially in low SNR, we proposed a two-step spectrum sensing in this paper. With dual-threshold energy detection for the primary band and cyclostationary detection for the confused area, the joint detection is proved to be good performance while there is noise uncertainty, and it has low computation requirement than cyclostationary detection.
