A method of estimating, by a user equipment (UE), a location of the UE in a wireless communication system is disclosed. The method includes measuring distances between a plurality of anchor nodes and the UE; creating a first matrix using values of the measured distances; creating a third matrix based on the first matrix and a second matrix, the second matrix being a centering matrix; and estimating the location of the UE based on a result of comparing a first value generated based on eigenvalues of the third matrix with a second value that is a pre-defined reference value, wherein when the first value is greater than the second value, all the measured distances are distances measured through a line of sight (LOS) path, wherein when the first value is less than the second value, some of the measured distances are distances measured through a non-line of sight (NLOS) path.
