ADAPTIVE COMMUNICATION APPARATUS

摘要

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.
