A method for wireless location measurement of a receiver is provided. The method includes: estimating radio channels of a plurality of frequency domains respectively corresponding to a plurality of transmitters by using received signals from the plurality of transmitters; extracting a plurality of propagation delay tab profiles based on the radio channels of the plurality of frequency domains; calculating the distance between each of the transmitters corresponding to the respective propagation delay tab profiles and the receiver by using the propagation delay tab profiles; and estimating the location of the receiver by using the distance between each transmitter and the receiver.
