WEIGHTED LEAST SQUARE LOCALIZATION METHOD EXPLOITING MULTIPATH CHANNEL STATISTICS FOR NON-LINE-OF-SIGHT MITIGATION

摘要

A method mitigates NLOS conditions based on weighted least squares (WLS) technique, in which the weights are derived from multipath components (MPCs) of the received signals. The weighting methodology can be used with both linear and non-linear least squares models, as well as different other NLOS mitigation schemes, such as residual based algorithms or maximum likelihood techniques.
