Abstract
The invention relates to a method for the frequency error correction of an oscillator of a sensor node in a sensor network, comprising the following steps: receiving a transmission signal of a transmitter, the signal being modulated by orthogonal frequency division multiplexing (OFDM); determining the frequency deviation of the oscillator using the received transmission signal; determining a correction signal for correcting the frequency deviation of the oscillator and correcting the frequency of the oscillator by means of the correction signal.
