MEHOD AND SYSTEM FOR RECOGNIZING RANDOM ACCESS BURST SIGNAL

摘要

The present disclosure discloses a method for identifying an access burst signal, and the method comprises: a receiving terminal performs a Time Advance (TA) estimation to baseband data of two signals respectively to obtain two TA values; and it is determined that the signal received by the receiving terminal is an invalid Access Burst (AB) signal when a difference between the two TA values is greater than a channel dispersion length. The present disclosure also discloses a method for identifying an access burst signal, and the method comprises: the receiving terminal performs demodulation to baseband data of two signals respectively; and it is determined that the signal received by the receiving terminal is a valid Access Burst (AB) signal when two demodulations to baseband data are both successful. The present disclosure also discloses two systems for identifying an access burst signal. The present disclosure can improve the correct recognition probability for the AB signal.
