In this paper, we consider time of arrival estimation of ultra-wideband signals based on low-rate samples that are obtained after a square-law device. Signal conditioning techniques based on a bank of cascaded multi-scale energy collection filters and wavelets are introduced, where correlations across multiple scales are exploited for edge and peak enhancements towards a more accurate detection. The performances of the discussed algorithms are tested on IEEE802.15.4a residential line-of-sight (LOS) channels. |
