Abstract
Provided are method and device for generating STF signals which can be used in a wireless LAN system. STF signals are comprised in a field which is used for improving AGC estimation of MIMO transmission. Some of the STF signals are used for uplink transmission and can be used for an uplink MU PPDU transmitted from a plurality of STAs. The provided STF signals are, for example, used for an 80+80 MHz or 160 MHz band and can be generated on the basis of a sequence in which a preset M sequence is repeated. The preset M sequence can be a 15-bit length binary sequence.
