Abstract
Certain implementations may include systems, methods, and apparatus for wirelessly transmitting data and power across inductive links using pulse delay modulation (PDM). According to an example implementation, a method is provided that includes generating a power carrier signal; generating a data waveform from a series of binary bits, the data waveform including a series of pulses in synchronization with the power carrier signal; transmitting, from one or more transmitting (Tx) coils of an inductive link, the power carrier signal and the data waveform; receiving, by one or more receiving (Rx) coils of the inductive link, an interference signal, the interference signal based at least in part on a superposition of the transmitted power carrier signal and the transmitted data waveform; determining zero crossings of the received interference signal; determining delays associated with the zero crossings; and determining the data packet based at least in part on the delays.
