ABSTRACT:
In a method for locating a position of a terminal with use of weak signals, a combined weight to be used to separate a path from others through correlation calculation is obtained from a plurality of delay profiles measured in course of time. The obtained weight is used to combine the delay profiles and a path detection is carried out on the combined delay profiles.
