Abstract: The present disclosure discloses a method and device for determining a position, and a computer storage medium. The method includes that a first power value for a SYNC-NL segment within a DwPTS, a second power value for a first GP segment which precedes the SYNC-NL segment, a third power value for a second GP segment which follows the SYNC-NL segment, and a fourth power value for a time slot 0 are acquired; an eigenvalue of the DwPTS is calculated according to the first power value, the second power value, the third power value and the fourth power value; and the position of the DwPTS is determined according to the eigenvalue.

Abstract: Disclosed are a multipath selection method and device, and a storage medium. The method includes that: a correlation sequence between a received signal and a local reference signal is acquired by means of a correlation calculation method; a power spectrum of the correlation sequence and an average noise power of the received signal are acquired; according to the average noise power of the received signal, the power spectrum of the correlation sequence is divided into at least one first multipath component area and a second multipath component area according to a pre-set dividing rule; the at least one first multipath component area is searched according to a pre-set first noise threshold, so as to acquire a valid multipath component signal in the at least one first multipath component area; and the second multipath component area is searched according to a pre-set second noise threshold, so as to acquire a valid multipath component signal in the second multipath component area.
