1. A power receiver executing in-band communication with a power transmitter, the power receiver configured to:
monitor the in-band communication to detect a change in frequency that identifies a training sequence;
dynamically determine one or more impulse responses received after the training sequence; and
cancel an effect of each of the one or more impulse responses during the in-band communication.
