为观察位置不准确的主要原因
The main reason for inaccuracies observed in location
estimation, imposed by the propagation conditions of the
wireless channel, is the Non Line Of Sight (NLOS) due to
transmitted signal blocking. Because of the NLOS, the first
TOA, which bears information related to the mobile
terminal position, suffers stronger attenuation than later
arrivals and therefore wrong timing information is
obtained yielding biased position estimation. Several
NLOS mitigation algorithms have been presented. One of
the most common approaches consists of correcting the
TOA measurements exploiting the fact that the variance of
the TOA measurements is significantly increased in NLOS
scenarios
