Zusammenfassung:	A power transmitter is provided. The power transmitter may synchronize a sampling start time to a pulse-width modulation signal. The power transmitter may determine an average sampling rate for sampling a power carrier signal. The power transmitter may sample the power carrier signal to obtain sample values. The power transmitter may process the sampled values. The average sampling rate may be N times a data rate. The power transmitter may process the sampled power carrier signal using two digital match filters to produce two separate digital match filter outputs. The power transmitter may determine an amplitude of peaks for the two separate digital match filter outputs. The power transmitter may determine an interval between bits for the two separate digital match filter outputs. The power transmitter may determine whether a transmitted bit is a '0' or '1'.
