AI Technical Summary
Technical Problem
Existing sequence transmission methods lack flexibility in downlink synchronization, random access, sensing, and radar systems, and cannot adjust the sequence transmission method according to requirements, thus affecting detection performance.
Method used
By determining N1 first sequences, the temporal position intervals of any two adjacent sequences may be equal or unequal. Combined with Gray complement pair GCP sequences, the temporal position intervals of the sequences can be flexibly adjusted to optimize the low-ambiguity region of the ambiguity function and improve detection performance.
Benefits of technology
It improves the flexibility and detection performance of sequence transmission methods, and enhances the detection accuracy of target object position and velocity.

Abstract
The invention discloses a sequence transmission method and device, which can improve the flexibility of a sequence transmission mode. The method comprises the following steps: a transmitting end device determines N1 first sequences, the (n ') th first sequence is determined according to the (n') th first base sequence, n '= 0, 1,..., N1-1, and each first base sequence is a sequence in GCP. The transmitting end device sequentially transmits N1 first sequences, time intervals between time domain positions where any two adjacent first sequences are located are equal, and the N1 first base sequences are related to a prime factor of N1 or the N1 first base sequences are predefined sequences; or at least an integer p, an integer q, and a time interval between the time domain position where the pth first sequence in the N1 first sequences is located and the time domain position where the sequence adjacent to the pth first sequence is located exist, the time interval between the time domain position where the qth first sequence in the N1 first sequences is located and the time domain position where an adjacent sequence of the qth first sequence is located is different, and p and q are larger than or equal to 0 and smaller than or equal to N1-1.
