MULTI-CARRIER COMMUNICATION METHOD AND COMMUNICATION APPARATUS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a multi-carrier communication method for adjusting arrangement for each block in response to the actual receiving state of a multi-carrier signal, in arranging a code block generated by error-correcting coding processing not only in a time axis direction but also in a frequency axis direction to improve an error correction rate of the multi-carrier signal, and to provide a communication method thereof. SOLUTION: A fluctuation amount of an SNR for each symbol in the time axis direction of the multi-carrier signal is observed in a maximum Doppler frequency detector 555, and a fluctuation amount thereof in the frequency axis direction is observed in a delay profile detector 557. The arrangement of the code block in the multi-carrier signal so that the fluctuation amount of symbol of the code block becomes small on the basis of these observed values in a fluctuation amount comparing section 559 and a request format determining section 560.
