Various signal processing systems may benefit from appropriate control based on selected parameters. For example, feedforward-based signal or noise cancellation systems may benefit from adaptive frequency band weighting within time domain. A method can include receiving an input signal that is to be transmitted over a channel. The method can also include calculating an instantaneous frequency of the input signal. The method can further include applying the instantaneous frequency as an adaptive parameter in an adaptation performed relative to the input signal. The method can additionally include providing an output signal based on the adaptation.
