Adaptive equalizer capable of effectively removing a remaining fading in an equalized signal.

摘要

In an adaptive equalizer (40) connected to a demodulator (14) to equalize a demodulated signal into an equalized signal in accordance with main and first through N-th controllable tap gains, where N represents a positive integer which is not less than one, the main and the first through the N-th controllable tap gains are produced dependent upon the demodulated and the equalized signals and are controlled by main and first through N-th parameters, respectively. A supplying circuit (42) supplies main and first through N-th values as the main and the first through the N-th parameters to the adaptive equalizer when the demodulator is put in a synchronization state. The supplying circuit supplies main and first through N-th additional values as the main and the first through the N-th parameters to the adaptive equalizer when the demodulator is put out of the synchronization state. <IMAGE>
