摘要： This invention relates to a space-time coding method for a UWB transmission system comprising two radiation elements. This method codes a block of information symbols (S=(a1,a2,a3,a4)) belonging to a PPM modulation constellation or a PPM-PAM composite modulation constellation with a number of time positions greater than or equal to 3, into a sequence of vectors (c10,c20,c11,c21), the components of a vector being intended to modulate a UWB pulse signal for a radiation element of said system and for a given transmission interval (Tf). A first and a second of said vectors are obtained by means of a first linear combination of a first and a second pair of said symbols, and a third and a fourth of said vectors are obtained by means of a second linear combination of said first and second pairs of said symbols, the first and the second linear combinations using scalar coefficients ({tilde over (α)}, {tilde over (β)}, −{tilde over (β)}, {tilde over (α)}) of which the corresponding ratios are approximately equal to the Golden number and to its opposite, the components of one of said vectors also being permuted according to a cyclic permutation prior to modulating said pulse UWB signal.
