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.

I. INTRODUCTION
Energy detector is a non-coherent approach for ultrawideband (UWB) signal reception, where low complexity
receivers can be achieved at the expense of some performance degradation [1]. As opposed to more complex
