| 摘要 |
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 = (a1,a2...,ap2)) belonging to a modulation alphabet M-PPM or composite modulation alphabet M-PPM-M'-PAM with M even, as a sequence of vectors (si, j, 7si, j) 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 (Tf). |
