1 results about "Golay sequence" patented technology

This application provides a communication method and a related apparatus, to reduce a quantity of bit storage units needed when correlation detection is performed on a preamble, a postamble, or a mid-amble. The method includes: A first device determines a first signal based on a first sequence and sends the first signal, where the first sequence and a first generalized Golay sequence meet a preset relationship, an n-level register is configured to generate the first generalized Golay sequence, a storage depth of a kth-level register in the n-level register is (I), a value of Pk is an integer from 0 to n-1, and a value of Pn is n-1; when i≄j, Pi≠Pj, where values of i and j are integers from 0 to n-1; and a value of k is any integer from 1 to n, n is a positive integer, a length of the first sequence is N, and N=2n. The first device receives the first signal, detects the first signal by using 1st-level to (n-1)th-level registers in the n-level register, and determines a start location and / or an end location of the first sequence in the first signal.
