Abstract:
A method of modulating a digital signal of width L in frequency on a given useful frequency band is described The digital signal is separated into N blocks bn (1≦n≦N). The given useful frequency band is split into N contiguous parts Pn. Channels Cn, of width 1n in frequency, lying within an associated part Pn, are defined. The channels Cn are separated, a distributing of each block of digital signals bn over the associated channel Cn.
