Abstract:
The present invention relates to a space-time coding method for a UWB transmission system comprising at least two radiated elements. This method codes a block of information symbols S=(a1, a2 . . . , aP2)) belonging to a 2-PPM modulation or 2-PPM-M′-PAM composite modulation alphabet with M′≧2, into a sequence of vectors (sl,j,Ωsi,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 (Tƒ).
