This paper introduces a new modulation technique, called pulse harmonic modulation (PHM), for wideband, low power data transmission across inductive telemetry links that operate in the near-field domain. The use of sharp and narrow pulses, similar to impulse-radio ultrawideband (IR-UWB) in the far-field domain, leads to significant reduction in the transmitter power consumption. However unlike IR-UWB,...
The significance of passive RFID labels is growing in logistic processes. While the initial aim was to identify items with an invariable identification code, new applications with enhanced functionality arise which need additional energy. This contribution investigates the requirements on an inductive coupled RFID radio link in order to provide a reliable power transmission under varying coupling...
