PROBLEM TO BE SOLVED: To obtain an adaptive equalizer capable of executing correct convergence determination, even if the C/N of a carrier power-to-noise power ratio changes. SOLUTION: The equalizer is configured so as to be provided with a threshold setting circuit 4 for setting a threshold for convergence determination according to an error between hard decision data and soft decision data. By this configuration, a convergence determining circuit 5 can determine a convergence state with a threshold for convergence determination corresponding to the C/N. As the result, the circuit exhibits an effect that correct convergence determination can be executed even if the C/N changes. COPYRIGHT: (C)2005,JPO&NCIPI
