Abstract
A backscatter radio system having a transceiver module and a transponder. The transceiver module is configured to generate and transmit a radio frequency pulse signal with Pulse Position Modulation (PPM). The generated radio frequency pulse signal includes a power and information transferring pulse and a time reference pulse within a dual symbol duration comprising a first and a second symbol periods. The power and information transferring pulse enables a power injection to a rectifier circuit in the transponder and the time reference pulse enables an excitation of a resonance signal in a resonance circuit in the transponder. A response radio frequency pulse signal with PPM is generated using the resonance signal generated in the resonance circuit with a time offset such that the first and second symbol periods are separated in the time domain.
