(EN) TRAINING SEQUENCES FOR VERY HIGH THROUGHPUT WIRELESS COMMUNICATION
(FR) SÉQUENCES D'APPRENTISSAGE PERMETTANT UNE COMMUNICATION SANS FIL À TRÈS HAUT DÉBIT
Abstract
(EN) Methods and systems for communications that generate a plurality of spatial streams, wherein each of the spatial streams comprises a data packet with a training sequence (Sk); and multiply at least a portion of the training sequence in each of the spatial streams with a different spreading sequence (Wmk). Methods and systems that receive a plurality of spatial streams, wherein each of the spatial streams comprises a data packet with a training sequence; multiply at least a portion of the training sequence in each of the spatial streams with a different spreading sequence; and decode the plurality of spatial streams based on the different spreading sequences.
(FR) La présente invention se rapporte à des procédés et à des systèmes pour des communications qui génèrent une pluralité de flux spatiaux, chaque flux spatial comprenant un paquet de données avec une séquence d'apprentissage (Sk); et multiplient au moins une partie de la séquence d'apprentissage dans chaque flux spatial avec une séquence d'étalement différente (Wmk). La présente invention se rapporte également à des procédés et à des systèmes qui reçoivent une pluralité de flux spatiaux, chaque flux spatial comprenant un paquet de données avec une séquence d'apprentissage; multiplient au moins une partie de la séquence d'apprentissage dans chaque flux spatial par une séquence d'étalement différente; et décodent la pluralité de flux spatiaux sur la base des différentes séquences d'étalement.
