Abstract: It is proposed a method for delay spread classification of an orthogonal frequency-division multiplexing signal (multiplexing signal), and a receiving device and a telecommunication device connected thereto, the multiplexing signal comprising at least a first multiplexing symbol comprising at least two first reference symbols in the frequency domain, the method comprising: receiving at least the first multiplexing symbol; demodulating at least the first reference symbols of the first multiplexing symbol; determining at least a first autocorrelation value by autocorrelating the demodulated first reference symbols in the frequency domain; computing the filtered output energy of the autocorrelation and classifying the delay spread by mapping the ratio of the output energy for the filters.
