TRANSMISSION METHOD, RECEIVING METHOD, TRANSFER METHOD, AND RECEIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a transfer method of an orthogonal frequency multiplexed signal and its receiving device capable of precisely correcting a reception level and/or fluctuations in frequency band without causing the erroneous decision of demodulated data as a result. SOLUTION: A specified symbol S0 having a predetermined specified pattern can be contained in an orthogonal frequency division multiplexing signal transferred from a transmission side to a reception side in addition to a symbol Sm including data to be transmitted. In the reception side, fluctuations in a reception level and/or fluctuations in the frequency band of the reception signal are detected and corrected based on a received specified symbol S0. Accordingly, the specified symbol S0 has a specified pattern, the fluctuations in the level and/or the fluctuations in the frequency band of the received signal can be precisely detected from the specified symbol S0, and high-accuracy correction can be performed as a result.
