The method according to the invention includes at least one symbol decoding step in the course of which at least one modulation value Pwk representative of an amount of power carried by each pulse sequence Tsgk is computed and compared to at least one predetermined threshold value thk1, thk2 . . . thkM(k). The method according to the invention enables to limit the processing time and power needed for performing the demodulation of a power-modulated UWB signal, since the information carried by such a signal may be recovered by a receiver without said receiver having to map precisely, with respect to time, the received pulse sequences.Other References
