<p>The present invention relates to a method of spatio-temporal coding for UWB transmission system comprising at least two radiative elements. This method codes a block of information symbols S = (a<SUB>1</SUB>,a<SUB>2</SUB>...,a<SUB>p2</SUB>)) belonging to a modulation alphabet M-PPM or composite modulation alphabet M-PPM-M' -PAM with M even, as a sequence of vectors ( s<SUP>i, j</SUP>, Os<SUP>i, j</SUP> ) the components of a vector being intended to modulate a pulsed UWB signal for a radiative element of said system and for a given transmission interval (T<SUB>f</SUB>).</p> |
