Comparison of Different Spectrum Sensing Techniques for Cognitive Radio Systems
نویسندگان
چکیده
In Cognitive radio networks, the optimum utilisation of the spectrum can be ensured by detecting the unused spectrum by spectrum sensing techniques and sharing it without harmful interference to other users. One important requirement in a cognitive radio network is sensing spectrum holes reliably and efficiently. This paper outlines the different spectrum sensing techniques like matched filter detection, energy detection and cyclostationary feature detection and compares the performance in presence of additive white Gaussian noise. The results are summarized in the concluding section.
