Abstract

In this paper, joint estimation of the optimal threshold, synchronization point, and integration interval is developed for ultrawideband (UWB) energy detectors employing on-off keying (OOK) modulation. Gaussian approximation of the received signal statistics is shown to enable low complexity solutions at the expense of some performance degradation. The performances of the optimal and suboptimal solutions are evaluated and compared. It is shown that explicit BER minimization is required for parameter optimization. Using simulations, number of training symbols required to converge to ideal parameter estimates is demonstrated to be increasing with increasing SNR. © Springer Science+Business Media B.V. 2007.
