Abstract
Disclosed are a method and an apparatus for generating an STF signal usable in a wireless LAN system. The STF signal is included in a field used to improve AGC estimation of a MIMO transmission. The STF signal that is suggested, for example, can be used for an 80 MHz band and can be generated based on a sequence in which a predetermined M sequence is repeated. Also, the disclosed STF signal can be used for a 1× STF signal from the 1× STF signal and a 2× STF signal. The predetermined M sequence can be a binary sequence of which the length is 15 bits.
