Low Complexity Enhanced Hybrid Spectrum Sensing Architectures for Cognitive Radio Equipment

Spectrum sensing enables detecting opportunities in licensed bands in order to access unused portions of the licensed spectrum. In this paper, the authors propose two low complexity detectors based on a combination of two well-known and complementary signal detection mechanisms: energy detection and mono-cycle detection, which exploits cyclostationarity property of the signals. In the first algorithm the mono-cycle detector iteratively corrects the thresholds of a double threshold energy detector that will finally converge to the performance of the mono-cycle detector.
