Title (EN) PILOT SIGNAL TRANSMISSION METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE TRANSMISSION DE SIGNAL PILOTE
Abstract: front page image
(EN)A pilot (or reference) transmission scheme is utilized where different transmitters are assigned pilot sequences with possibly different cyclic time shifts. A pilot signal is transmitted concurrently by the transmitters in a plurality of pilot blocks, and a receiver processes the plurality of received pilot blocks to recover a channel estimate for at least one of the transmitters while suppressing the interference due to the pilot signals from the other transmitters.
(FR)L'invention concerne un schéma de transmission pilote (ou de référence) qui sert à affecter à différents émetteurs des séquences pilotes ayant éventuellement différents décalages circulaires dans le temps. Les émetteurs acheminent en simultanéité le signal pilote dans une pluralité de blocs-pilotes, et un récepteur se charge de traiter la pluralité de blocs-pilotes reçus afin de récupérer la valeur estimative d'un canal pour l'un au moins des émetteurs tout en supprimant les interférences causées par les signaux pilotes provenant des autres émetteurs.
