WebOct 21, 2009 · Improving source localization in LOS and NLOS multipath environments for UWB signals Abstract: The presence of undetected direct path conditions in the TOA (Time of Arrival)-based indoor geolocation introduces major errors into distance measurements. WebAug 4, 2009 · A LOS path, also called a direct path (DP), is a straight line path that connects the transmitter and the receiver. With the absence of the LOS path, the transmitted signal could only reach the receiver through penetrated, reflected, diffracted, or scattered paths called non-line-of-sight (NLOS) paths.
