    Abstract: Proposed is a method and device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA through a broadband and decodes the PPDU. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. The first STF sequence is a sequence including an M sequence and is defined as {M 1 −M 0 −M 1 −M 0 M 1 −M 0 −M 1 −M 0 −M −1 M 0 M −1 M 0 −M −1 M 0 M −1 M}*(1+j)/sqrt(2).
