An apparatus for determining a relative position of a wireless power transmitter from a wireless power receiver is provided. The apparatus comprises a plurality of sense coils, each configured to generate a respective signal under influence of an alternating magnetic field comprising a plurality of wave pulses, each wave pulse occurring in a respective time slot of a plurality of time slots. The apparatus further comprises a processor configured to determine the relative position of the wireless power transmitter from the wireless power receiver based on the respective signal from each of the plurality of sense coils.
