Abstract: A sequence generation method, includes: generating a PPDU which comprises a matrix-mapped EHT LTF sequence, the matrix-mapped EHT LTF sequence is obtained by multiplying a predefined EHT LTF sequence by a P matrix, the P matrix is an n×n matrix, and n is greater than 8; and sending the PPDU, therefore the matrix-mapped EHT LTF sequence in a PPDU has a low PAPR value.
