Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

Non-line-of-sight (NLOS) and dense multipath problems are the major challenges for the millimeter wave (mm-wave) indoor ranging systems. To acquire time of arrival (TOA) estimate accurately in such a poor environment, an improved statistics fingerprint analysis algorithm for energy-based timing estimation and artificial neural network (ANN) based ranging error mitigation is presented in this paper. The developed algorithm can obtain TOA estimate accurately by measuring the kurtosis, skewness, standard deviation, minimum slope, and gradient of the received mm-wave pulses. ANN is employed to mitigate the ranging error based on the obtained nonlinear regression between the thresholds and the analyzed characteristics of mm-wave pulses. The presented numerical simulation results indicate the proposed algorithm can achieve significant performance improvements in both line of sight and NLOS channels of the IEEE 802.15.3c standard, as compared to conventional algorithms.
