Abstract
This invention relates to a space-time coding process for a pulse type MIMO-UWB system using symbols belonging to a PPM modulation alphabet. Orthogonality of signals emitted by the different antennas is achieved by providing a mechanism for permutation of PPM symbol modulation positions and by imposing a constraint on the positions of said symbols. The space-time coding process according to the invention enables an incoherent type reception.
