PROBLEM TO BE SOLVED: To provide an orthogonal frequency division multiplexing transmission device and generation and transmission method of preamble signal. SOLUTION: The preamble signal for generating and transmitting the preamble signal has at least one first portion and at least one second portion. The last six complex symbols of the first portion and the second portion are (1-i), (-1, -i), (1-i), (-1-i), (-1+i), (1+i), and a sequence of the complex symbols of the second portion satisfies S<SB>-26</SB>,<SB>+26</SB>=N*ä0, 0, S1, 0, 0, 0, S2, 0, 0, 0, S3, 0, 0, 0, S4, 0, 0, 0, S5, 0, 0, 0, S6, 0, 0, 0, 0, 0, 0, 0, S7, 0, 0, 0, S8, 0, 0, 0, S9, 0, 0, 0.
