A wireless transmitting device for use in communication with a wireless receiving device with a wireless packet, includes a plurality of antennas, and a signal generator to generate a signal for the wireless packet, which includes an AGC preamble sequence and data using a plurality of subcarriers. A value at a time "t" of a signal in a time domain of the AGC preamble sequence transmitted from an i<SUB>Tx</SUB>-th antenna (where i<SUB>TX</SUB>=1, 2, 3 . . . ), is formed by a cyclic shift for each the antennas in the time domain.
