Multicarrier transmission system, with modifiable bandwidth

Abstract

A communication method in an orthogonal frequency division multiplexing modulation communication system includes a transmission apparatus (1, 2T, 3A, 3B, 5, 8, 11, 13T) in which a frequency bandwidth of a signal modulated in accordance with an orthogonal frequency division multiplexing modulation system is changed and the modulated signal is transmitted and a receiving apparatus (9, 4, 12, 3C, 2R, 7, 13R) in which the modulated signal is received and a frequency bandwidth for demodulation of the received signal is changed to follow the change of the frequency bandwidth of the modulated signal.
