In this paper, we proposed a cognitive radio (CR) implementation by using standard wireless communication laboratory equipments such as signal generator and spectrum analyzer. Equipments are controlled through MATLAB instrument control toolbox to carry out CR capabilities specified by IEEE 802.22 WRAN standard. Energy detection and maximum minimum(More)
Kalman filtering (KF) is a form of recursive estimator, which has been widely applied to different applications. This paper discusses a new approach, based on a discrete event process, for tracking of threats (emitters). Pulses of a particular threat from received mixed (raw) pulse sequences of multiple threats corrupted by timing jitter and measurement(More)
Detection of primary services is important for the access of unlicensed/secondary services to TV bands in order to increase spectral efficiency. We proposed a weak wireless microphone signal detector based on higher-order spectral (bispectral) analysis. In order to reduce complexity, we estimated the bispectrum through the use of direct method and detection(More)
