Abstract

In this paper, we propose a method to estimate the threshold value for energy detector (ED) and kurtosis detector (KD) in impulse radio ultra-wideband on-off keying (OOK) scheme. Estimation of threshold value is obtained from the parameters of the probability density functions (PDF) of two hypotheses in OOK signaling. Gaussian and lognormal distributions are used for ED receiver and KD receiver, respectively. Symbols are transmitted in packets and the PDF’s parameters of the hypotheses are estimated by using training symbols in each packet. The approximation of the threshold value is obtained by using these parameters. Simulation results show that the estimated threshold has high accuracy for different amounts of signal to noise ratios and integration intervals.
