Implementation and Analysis of Spectrum Sensing Using Energy Detection Method

摘要

The continuously increasing demand for wireless communication has highlighted the problem of underutilization of available spectrum. Cognitive radio technology provides a solution to this problem by utilizing the white spaces in the spectrum and allowing the unlicensed user to share licensed spectrum. There are various techniques to sense the licensed spectrum; one such technique is energy detection method. The performance parameters in spectrum sensing are probability of detection and probability of false alarm. This paper explores the performance of energy detection method in case of LOS communication and NLOS communication.
