1. A method for estimating a propagation delay time using signal transmission/reception, comprising:

  • receiving an initial reception signal or a signal of which frequency offset is compensated according to a predetermined condition;

    detecting a peak time of a received signal;

    estimating frequency offset of the signal from which the peak time is detected;

    compensating the frequency offset of the signal from which the peak time is detected; and

    compensating the peak time of the received signal by redetecting the peak time of the received signal of which the frequency offset is compensated.
