PROBLEM TO BE SOLVED: To provide an adaptive interference canceler which can improve its transmission characteristics and also is excellent in stability. SOLUTION: A desired signal is produced by a desired signal detection means DSC-DET and supplied to a complex conjugate generation means CC where a desired complex conjugate signal is produced. The multipliers 301 to 30n perform the adverse modulation of output signals X1(i) to Xn(i) by means of the desired complex conjugate signal and convert the included desired signal components into the low band frequency. Then these signal components are eliminated by high pass filters HPF1 to HPFn . Thus the output signals X1'(i) to Xn'(i) of the multipliers 311 to 31n contain only the interference signal components. Based on these generated interference signal components, the interference signal components are canceled. |
