Detection of a pilot sequence on simple computing devices

A data receiver of a digital communication system, the data receiver comprising:

• a data receiver device,
• wherein the data receiver device is configured to detect a pilot signal, wherein, for at least one partial transfer duration of a transfer duration of the pilot signal, the pilot signal is located at only one radio frequency of a plurality of different radio frequencies of a frequency-shift keying method used for data transfer by a data transmitter, by mapping all symbols of the pilot signal to the same frequency line,
• wherein the data receiver device is configured to detect the pilot signal based on output bins of a DFT (discrete Fourier transform) of FFT (fast Fourier transform) formed over at least the partial transfer duration of the pilot signal, and
• wherein the partial transfer duration corresponds to at least two symbol durations, at least three symbol durations, or at least four symbol durations, of a data transfer of the data transmitter.

A data transmitter of a digital communication system, the data transmitter comprising:

• a data transmitter device,
• wherein the data transmitter device is configured to transfer data using a frequency-shift keying method;
• wherein the data transmitter device is configured to transmit a pilot signal, wherein the pilot signal comprises an MSK-modulated or GMSK-modulated pilot sequence, wherein MSK-modulated denotes minimum shift key-modulated, wherein GMSK-modulated denotes Gaussian minimum shift key-modulated, and wherein the MSK-modulated or GMSK-modulated pilot sequence is based on one of the following binary sequences:
• 0000 0000,
• 1111 1111,
• 0101 0101,
• 1010 1010,
• 0000 0000 0000 0000,

• 1010 1010 0000 0000, and
• 1010 1010 1111 1111;
• wherein, for at least one partial transfer duration of a transfer duration of the pilot signal, the pilot signal is located at only one radio frequency of a plurality of radio frequencies of the frequency-shift keying method used for the data transfer by the data transmitter device, by mapping, for the at least one partial transfer duration, all symbols of the pilot signal to the same frequency line;
• and
• wherein the partial transfer duration corresponds to at least two symbol durations, at least three symbol durations, or at least four symbol durations, of the data transfer of the data transmitter device.
