  • PULSE EDGE MODULATION
    Publication number: 20100290516
    Abstract: Systems and methods for the pulse edge modulation of digital carrier signals for communications systems which are useful in body implanted electronics. A digital carrier signal is generated and the carrier is pulse edge modulated with digital data. A pulse edge modulated signal is generated by either retarding or advancing each pulse edge of a carrier to be modulated relative to its original position in time, depending on the state of the digital bit to be modulated on that edge.

  • PULSE EDGE DEMODULATION
    Publication number: 20100290517
    Abstract: Systems and methods for the demodulation of pulse edge modulated signals for communications systems which are useful in body implanted electronics. A pulse edge modulated signal is generated by retarding or advancing each pulse edge of a carrier to be modulated relative to its original position in time, depending on the state of the digital bit to be modulated on that edge. Each modulated edge of a pulse edge modulated signal is demodulated by determining the position in time of the modulated edge relative to the original respective position of the modulated edge prior to modulation.
