The method includes a step of generating a magnetic signal with an electromagnetic functional unit, wherein the electromagnetic functional unit is an actuator of a loudspeaker of the device or wherein the electromagnetic functional unit is an electromagnetic resonant circuit connected to the device, wherein the magnetic signal carries the data to be transferred from the device to the other device: Furthermore, the method includes a step of detecting the magnetic signal with an electromagnetic resonant circuit of the other device in order to obtain the data to be transferred from the device to the other device, wherein the magnetic signal is FSK-modulated, wherein a resonance frequency of the electromagnetic resonant circuit of the other device and a carrier frequency of the FSK-modulated magnetic signal are tuned with respect to each other.

Efficient communication to configure sensor nodes

Embodiments provide a data receiver, wherein the data receiver is configured to receive a broadband signal, wherein the broadband signal includes at least two partial data packets that are distributed in time and/or frequency, wherein the data receiver is configured to perform detection of the at least two partial data packets in the broadband signal and to provide at least one detection parameter for the detected partial data packets, wherein the data receiver is configured to perform decoding of the detected partial data packet by using the at least one detection parameter, wherein the data receiver is configured to perform or process detection and decoding separately from one another.

Packet detector/decoder for a radio transmission system

A transmitter for transmitting an output signal includes first and second filter structures. The first filter structure includes a first combiner to extend a first data signal by a first reference signal to obtain a first extended data signal, and a first IIR filter for filtering the first extended data signal to obtain a first filtered data signal. The second filter structure includes a second combiner to extend a second data signal by a second reference signal, and a second IIR filter for filtering the second extended data signal. The transmitter includes a multiplexer for combining the first and second filtered data signals to obtain the output signal. A system response of the first IIR filter based on the first reference signal corresponds to a system response of the second IIR filter based on the second reference signal.
