摘要：PROBLEM TO BE SOLVED: To provide an unwanted component reduction system.SOLUTION: A signal processing apparatus for reducing the impact of an unwanted signal component on a wanted signal component, includes: an input configured to receive an input signal having the wanted signal component and the unwanted signal component; an output configured to output an output signal; a first processor configured to process the input signal by operating on the input signal with a function that includes a term descriptive of the unwanted signal component to create an estimated unwanted signal; a second processor configured to process the estimated unwanted signal and at least one of the input signal or the output signal to identify one or more parameters to apply to the estimated unwanted signal to generate a correction signal; a correction signal generator configured to generate the correction signal on the basis of the one or more parameters; and a combiner configured to combine the input signal and the correction signal to form the output signal.
