UWB communication system cooperative non-coherent type.

摘要

Cooperation procedure between terminals in a telecommunication system UWB pulse, characterized in that a source terminal transmits a data symbol for a destination terminal in the form of signal, called a source signal, constituted by a sequence of identical frames, said sequence corresponding to a time symbol, each frame containing a pulse modulated in position by means of a PPM modulation alphabet, and in that a relay terminal, receiving said source signal, detects a modulation position of a pulse in at least one frame of the received signal, called first position, and transmits a relayed signal containing, in at least one predetermined subsequent frame of said symbol time, a pulse whose position, called the second position, is obtained from the first position by a permutation of the PPM modulation alphabet .
