1. A method comprising
providing a first Ultra-Wideband (UWB) transceiver which incorporates:
a filter circuit comprising an input port electrically coupled to an antenna for receiving UWB signals and an output port where the filter circuit processes the received UWB signals to generate processed UWB signals;
a clock source; and
an energy detector circuit electrically coupled to the output port of the filter circuit and the clock source; and
a digital signal processing (DSP) circuit coupled to the energy detector circuit; wherein
the first UWB transceiver receives an echo signal generated by a second UWB transceiver in response to a signal transmitted by the first UWB receiver;
the DSP executes a process comprising:
establishing the energy within integration time windows that are established in dependence upon a clock signal generated by the clock source;
establishing an estimate of an elapsed time between transmission of the signal and receipt of the echo signal, the estimate of the elapsed time being established in dependence upon an energy distribution determined by the DSP for two consecutive integration time windows during which the echo signal is received; and
establishing a range between the first UWB transceiver with a second UWB transceiver with another process employing the estimate of the elapsed.
