1. A method for localization of a mobile terminal, comprising: receiving signals transmitted between the mobile terminal and a plurality of fixed terminals; for each received signal, using a statistical metric, determining a likelihood that the received signal traveled a line-of-sight path; and determining the position of the mobile terminal based on the times-of-arrival of the received signal using a localization algorithm based in part on the likelihoods of line-of-sight path for the received signals.
