20090110050 | SPACE-TIME CODING METHOD USING A PARTITIONED POSITION MODULATION ALPHABET - The invention relates to a space-time coding method for a MIMO-UWB system with P antennas using information symbols belonging to an M-PPM, where M is a multiple of P. The modulation alphabet is partitioned into P sub-alphabets corresponding to successive ranges of modulation positions. An extension of the initial alphabet is obtained by forcing the information symbols to belong to some sub-alphabets, thereby increasing the binary rate of said system. | 04-30-2009 |

20090103589 | Incoherent type mimo UWB communication system - 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. | 04-23-2009 |

20080232455 | Maximum likelihood decoder for pulse and amplitude position modulation multi-source system - The present invention concerns a sphere decoder for maximum likelihood receiver intended to receive M-PPM-M′-PAM symbols at M modulation positions and at M′ amplitude levels from a plurality P of sources. The sphere decoder uses a Schnorr-Euchner type enumeration adapted to classify the points of a multidimensional PPM-PAM modulation. | 09-25-2008 |
20090046774 | SPACE-TIME CODING/DECODING METHOD FOR MULTI-ANTENNA PULSE TYPE COMMUNICATION SYSTEM - A space-time coding method for a UWB pulse type transmission/reception system. The space-time code, given for P=2, 4 or 8 transmission antennas, makes it possible to code 2-PPM information symbols and to modulate the position of UWB pulse signals using coded symbols, without requiring extension of the modulation alphabet. The space-time code is real with maximum diversity, and is full speed. The space-time decoding method is capable of estimating the information symbols thus transmitted. | 02-19-2009 |
