FIELD: radio engineering, communication.SUBSTANCE: present invention relates to mobile communication. The method of determining a packet message signal comprises the following steps: a receiving terminal estimates time advance (TA) for the source bandwidth data of two signals, respectively, to obtain two TA values; determining that the signal received by the receiving terminal is a false packet message signal (AB), if the difference between the two TA values is greater than the channel dispersion length. The present invention also discloses a method of determining a packet message signal, comprising the following steps: a receiving terminal demodulates the source bandwidth data of the two signals, respectively; determining that the signal received by the receiving terminal is the authentic packet message signal (AB) if both demodulations of the source bandwidth data are successful.EFFECT: improved correct determination of a packet message signal (AB).17 cl, 6 dwg |
