Abstract

Disclosed in the embodiments of the present application are a method and a device for eliminating non-line of sight (NLOS) in time of arrival (TOA) measurement values, and a terminal. The method includes: modeling a probability density of the first TOA measurement values from each base station to a terminal into a Gaussian mixture model, and selecting the TOA measurement values modeled into the Gaussian mixture model; performing NLOS identification on the selected TOA measurement values to obtain an identification label; and the identification label is used to indicate whether the selected TOA measurement values correspond to NLOS; and correcting the selected TOA measurement values according to the identification label, to eliminate errors caused by NLOS in the selected TOA measurement values.
