<p>PROBLEM TO BE SOLVED: To provide an interference signal eliminating unit by which an interference signal is eliminated from an input signal including a wide-band desired signal elimination of and a narrow-band interference signal, so that this unit enables suppression of elimination of the desired signal. SOLUTION: This unit provides an extraction means 11 which extracts an interference signal from an input signal, an elimination means 12, which eliminates the extracted interference signal from the input signal, an extraction control means 13 which controls the extraction of the interference signal by the extraction means 11 based on the elimination result, and an extraction quantity suppressing means 14, which suppresses the extraction quantity of the interference signal, based on the input signal; and for example the extraction control means 13 operates the control vectors consisting of the plural digital control values controlling the extraction of the interference signal and outputs the result to the extraction means 11, the extraction means 11 extracts the inner product of the input vectors consisting of plural input signal values and the control vector as the interference signal, and the extraction quantity suppressing means 14 limits the effective word length of the digital control value which consists of the control vector.</p> |
