Webextensive multipath conditions, the emphasis is placed on the behavior of the first path and the channel conditions are classified as Dominant Direct Path (DDP), Nondominant Direct Path (NDDP) and Undetected Direct Path (UDP). Webmeasurement of the direct path (DP) between a number of reference sources and the people or assets of interest. However, the rich multipath environment often causes the received signal strength (RSS) of indirect paths being greater than that of the direct path, sometimes resulting in undetected direct path (UDP) conditions [2].

Webgeolocation applications, TOA of the direct path (DP) is an important feature. However, due to certain obstructions between the transmitter and the receiver, such as metallic objects, the power of the DP and the nearby MPCs may be reduced below detection threshold. This leads to a condition called undetected-direct-path (UDP) causing large ranging WebSep 17, 2007 · In general, as the bandwidth increases beyond a certain value, it is expected that the measured TOA error approaches zero. However, for the so-called undetected direct path (UDP) conditions, the system exhibits substantially high distance measurement errors that cannot be eliminated with the increase in the bandwidth of the system.
