Techniques for transmitting data and training sequence efficiently using new slot and block formats are described. A transmitter (110) processes (e.g., encodes, interleaves, and partitions) a data block to obtain multiple output blocks. For each output block, the transmitter (110) generates multiple bursts having a training sequence that is shared by these bursts. The transmitter (110) sends the multiple bursts for each output block in multiple time slots, e.g., consecutive time slots in one frame. The multiple bursts for each output block may (1) include one or more short training sequences, (2) omit guard periods between adjacent bursts, (3) include a first tail bit field at the start of the first burst and a second tail bit field at the end of the last burst, (4) include at least one stealing flag field, or (5) have any combination of the above.

L'invention porte sur des techniques efficaces de transmission de données et de séquences d'apprentissage utilisant de nouveaux formats créneaux et blocs. Un émetteur (110) traite (par exemple, code, entrelace et partitionne) un bloc de données pour obtenir plusieurs blocs de sortie. Pour chaque bloc de sortie, l'émetteur (110) génère plusieurs rafales à séquence d'apprentissage unique partagée par l'ensemble des rafales. L'émetteur (110) envoie les rafales de chaque bloc de sortie dans plusieurs créneaux temporels, par exemple, des créneaux temporels consécutifs d'une trame. Les différentes rafales de chaque bloc de sortie peuvent (1) comprendre une ou plusieurs séquences d'apprentissage courtes, (2) ne pas utiliser les périodes de garde entre les deux rafales consécutives, (3) comprendre un premier champ de bits d'extrémité au début de la première rafale et un second champ de bits d'extrémité à la fin de la dernière rafale, (4) comprendre au moins un premier champ d'indicateurs furtifs ou (5) posséder une combinaison quelconque de ces éléments.
