<p>A wireless transmission method for improving the reception characteristic of a preamble. The wireless transmission method allows the patterns of subcarriers (transmitting antenna Tx1: 1, 2, 3, 5, 6, 7, 8, , transmitting antenna Tx2: 4, 9, 10, 12, 13, 14, ) in which preamble sequences are continuously arranged to be changed in a frequency direction. With this, the preamble sequences can be arranged at random subcarrier intervals and, when the autocorrelation values of the preamble sequences are obtained in a time domain, the peak value of the sidelobe becomes small, thereby making it possible to prevent a timing detection error.</p> |
