A space-time coding method for a UWB transmission system comprising at least two radiated elements. The method codes a block of information symbols S=(a1, a2 . . . , ap2)) belonging to an M-PPM modulation or M-PPM-M'-PAM composite modulating alphabet with M being even, into a sequence of vectors (si,j,Omegasi,j), the components of a vector being intended to modulate a UWB pulse signal for a radiative element of said system and for a given transmission interval (Tf).
