Abstract

In an embodiment a method includes transmitting a signal train through a medium, wherein the signal train includes a sequence of waves of a first group and of a second group, the first and second groups being shifted in a time domain according to a predetermined phase shift, receiving the signal train as a received signal train and as a function of time, detecting a phase shift in the received signal train, assigning wave periods of the received signal train to respective wave periods of the first group using the detected phase shift as reference and determining a sequence of time-of-flight signals from the sequence of waves of the first group and the assigned wave periods of the received signal train, respectively.
