Abstract

Spectrum sensing can be used to find free channels in cognitive radio systems. The localization algorithm based on double-thresholding (LAD) signal detection methods have been proposed to be used for spectrum sensing. Even though being widely studied, the performance of the LAD methods has not been studied in realistic channels. In this paper, ETSI BRAN/WLAN channel models B and C are used to study the performance of the LAD methods in the presence of realistic multipath, fading and Doppler effects in order to get statistical information about their performance. Measurements at the WLAN bands verify that the LAD methods have a good performance even in multipath situations.

Keywords: narrowband signal signal detection energy measurement multipath channels
