The invention relates to a device for transmission of data on a frequency spectrum divided into a plurality Nof spectrum fragments (f, f) each of which covers a frequency band, the frequency bands being discontiguous. The device comprises a packet generator configured to generate a data packet comprising a payload and at least one occurrence of a constant envelope signalling sequence. Said sequence, for example a modified Zadoff-Chu sequence, comprises N complex symbols and consists of a plurality of complex symbol sets each associated with one of the spectrum fragments. Each set comprises N/Nf complex symbols and each complex symbol of a set comprises a scaling term to the frequency band covered by the spectrum fragment associated with this set and a spectral transposition term in the frequency band covered by the spectrum fragment associated with this set.
