Meenakshi Sansoy, Avtar Singh Buttar

Abstract


Cognitive Radio plays an important role in the efficient utilization of limited spectra. Spectrum sensing can be d one with a number of techniques available like Energy Detection, Match Filter, Cyclostationary Detection, Wavelet Packet detection, etc. This paper includes the analysis of two basic techniques i.e., Energy Detection (ED) and Cyclostationary Feature Detection (CFD). The study focuses on the theoretical aspect of both the techniques supported by their simulation results. Results show the better performance of Cyclostationary Feature Detection in low SNR regime.
