INTERFERENCE SIGNAL ELIMINATING UNIT

摘要

PROBLEM TO BE SOLVED: To provide an interference signal elimination unit which eliminates interference signal from an input signal but suppresses which includes a wide- band desired signal the elimination of a narrow-band interference signal, so that this unit enables suppression of elimination of the desired signal. SOLUTION: For example, in the interference signal elimination unit provided in a receiving set an extraction means 1 extracts an interference signal V(t) from an input signal r(t); an elimination means 2 eliminates the extracted interference signal V(t) from the input signal r(t); an extraction control means 3 controls the extraction of the interference signal by the extraction means 1 based on the elimination result e(t) of the elimination means 2; and an extraction quantity suppressing means 4 suppresses the extraction quantity of the interference signal by the extraction means 1, based on the input signal r(t).
