Abstract
A method for a receiving node to find a distance from a transmitting node and measure a location includes: measuring a delay tab by receiving a location measurement signal from the transmitting node, temporarily determining a distance between the receiving node and the transmitting node by using the delay tab to compare it with a reference distance, selecting one of a distance estimation method using propagation delay and a distance estimation method using delay spread, and estimating a final distance.
