The invention discloses a transmission device and a method for transmitting a data frame, which relates to the communication field. The specific scheme is that the acquisition unit acquires LTF parameters, and obtain subcarrier starting position distribution of I; the LTF parameters include: LTF sequence generation required frequency transformation parameters and time domain parameters; frequency conversion unit according to the frequency domain transform parameters and the initial position of the I, the LTF sequence in frequency domain transform LTF time domain symbols; transform unit according to the time domain parameters of LTF symbols are the time domain LTF sequence; the sending unit to carrying a LTF sequence in the first data frame is transmitted to the second device, so that the second equipment according to the sequence of LTF LTF to determine the basic sequence and channel estimation based on LTF sequence. The invention is used in the transmission process of data frames.
