An adaptive communication apparatus for use in a multicarrier transmission system in which data sequence to be transmitted is divided into a plurality of data sequences, and these data sequences are converted into a high-frequency signal including a plurality of carriers allocated different frequencies and radio-transmitted in parallel. In the adaptive communication apparatus, a received high-frequency signal is separated into a plurality of carriers by a wave separator. The frequency characteristic of the received high-frequency signal is corrected by a frequency characteristic compensation unit. The frequency characteristic compensation unit is controlled by a controller through use of the high-frequency signal subjected to signal processing by the frequency characteristic compensation unit and the wave separator. The high-frequency signal thus processed by the frequency characteristic compensation unit and the wave separator is demodulated by a demodulator in order to output a plurality of data sequences corresponding to the respective carriers. The original data is reproduced by a parallel-to-serial converter from the plurality of data sequences corresponding to the respective carriers.

[ What is claimed is:] [1.] An adaptive communication apparatus for use in a multicarrier transmission system in which a data sequence to be transmitted is divided into a plurality of data sequences, converted into a high-frequency signal including a plurality of carriers with different frequencies and radio-transmitted in parallel, said apparatus comprising:a wave separator for separating a received high-frequency signal into a plurality of carriers;a frequency characteristic compensation unit for correcting frequency characteristic of the received high-frequency signal;a controller for controlling said frequency characteristic compensation unit through use of the high-frequency signal subjected to signal processing by said frequency characteristic compensation unit and said wave separator;a demodulator for demodulating the high-frequency signal thus signal-processed by said frequency characteristic compensation unit and said wave separator in order to output a plurality of data sequences corresponding to the respective carriers; anda parallel-to-series converter for producing one data sequence from the plurality of data sequences corresponding to the respective carriers;wherein the received high-frequency signal that includes the plurality of carriers is first input to said frequency characteristic compensation unit in order to correct the frequency characteristic of the high-frequency signal; the corrected signal is then input to said wave separator in order to obtain signals corresponding to the respective carriers; and the obtained signals are input to said controller and said demodulator.
