Abstract
A method for estimation a time-of-arrival of a radio signal is provided. The signal is an ultra-wideband (UWB) signal. The method uses kurtosis of the received signal to estimate an energy threshold of the signal. The energy threshold can be used to determine a time-of-arrival of the signal.
