Abstract
A method and an apparatus for transmitting a physical layer protocol data unit (PPDU) are provided. The method includes: generating a synchronization header field based on a first sequence or a third sequence, where a side lobe of a periodic cross-correlation function of the first sequence and a second sequence is a constant value, the first sequence is a binary sequence consisting of 1 and 0, the second sequence is a binary phase shift keying sequence corresponding to the first sequence, a side lobe of a periodic autocorrelation function of the third sequence is a constant value, and the third sequence is a binary phase shift keying sequence consisting of 1 and −1; and sending the PPDU on a target channel, where the PPDU includes the synchronization header field.
