Sequence detection method and device, and computer storage medium

Disclosed are a sequence detection method and device, and a computer storage medium, the method comprising: i-path data is obtained, the degree of parallelism being i; x th i-path data is stored; x th +1 i-path data is received; the x th i-path data and the x th +1 i-path data form an x th detection data set; s-path data continuously distributed in the detection data set is extracted within each of n detection windows, forming n data segments; a correlation operation is performed between each data segment and a local sequence; according to a result of the correlation operation, it is determined whether a data segment is a target sequence, wherein x is an integer not less than 1, i is an integer not less than 2, n is less than or equal to i, and s is an integer not less than 1 and equal to the bit number of the target sequence.
