Abstract
The non-coherent ultra-wideband receiver receives an ultra-wideband (UWB) signal, consisting of pulses (or 'symbols') and uses on-off keying (OOK) modulation so that when a binary '0' is transmitted, the receiver collects noise-only samples. The receiver collects samples during the symbol (pulse) duration and sorts the samples by magnitude of voltage or energy. The receiver uses the known transmission rate and the estimated signal-to-noise ratio to retrieve a sample index from a look-up table. The receiver then compares the signal sample at the index value with a predetermined threshold voltage (or energy). If the selected sample exceeds the threshold, then it is assumed that all succeeding samples also exceed the threshold (assuming the sort is in ascending magnitude) and the pulse is present and binary '1'. Otherwise, the pulse is absent in the sampling period, and binary “0”. The process is repeated for the signal duration.
