TRANSMISSION DEVICE, RECEPTION DEVICE, AND OFDM TRANSMISSION METHOD

摘要

SP signals to be transmitted from a first transmitting antenna 11 are arranged in the same pattern as SP signals to be transmitted from a second transmitting antenna 12. The SP signals to be transmitted from the second transmitting antenna 12 in one symbol are generated, such that the polarity of the SP signals are alternately inverted and non-inverted with respect to the SP signals to be transmitted from the first transmitting antenna 11 in the same symbol. Thus, in the direction that the symbol number is incremented by 1 and the carrier number is incremented by 3, the polarity of SP signals transmitted from the second transmitting antenna 12 are all inverted or non-inverted with respect to the polarity of corresponding SP signals transmitted from the first transmitting antenna 11.
