Abstract
According to an embodiment, a first signal processing apparatus includes one or more hardware processors configured to function as a signal processing unit, a first signal adjustment unit, and an update unit. The signal processing unit is configured to perform first signal processing on an input signal in which a second signal is superimposed on a first signal using at least one parameter and to output a first restoration signal obtained by restoring the first signal. The first signal adjustment unit is configured to multiply at least one of the first signal and the first restoration signal by a weighting coefficient and to output a corrected first signal and a corrected first restoration signal. The update unit is configured to update the at least one parameter using an error between the corrected first signal and the corrected first restoration signal.
