Systems and methods are provided for adaptively filtering a signal. A signal is received, and the received signal is filtered to generate an output signal. A difference signal is generated based on a difference between the output signal and a reference signal, and a correlation of the received signal and the different signal is evaluated. Then, a mode is selected between a first adaptive filtering mode and a second adaptive filtering mode based at least in part on the correlation, and the received signal is filtered using the selected adaptive filtering mode.
