Abstract
(EN)
A free slot detecting unit (119) informs a timing control unit (115) of a free transmission slot, if detected, in which user data to be transmitted is not assigned in a transmission signal framed by a communication framing unit (118), and changes a switch (121) to transmit a UW generated by a UW framing unit (120) to an end communication station. The end communication station estimates the propagation circumstance by using the UW, and perform predecoding.
(FR)
Cette invention concerne une unité de détection de créneau libre (119) qui va informer une unité de commande de synchronisation (115) de la présence d'un créneau de transmission libre, s'il est détecté, dans lequel les données d'utilisateur à transmettre ne sont pas attribuées dans un signal de transmission verrouillé en trame par une unité de verrouillage de trame de communication (118). L'unité de détection va ensuite modifier un commutateur (121) afin de transmettre un UW, généré par une unité de verrouillage de trame d'UW (120), vers une station de communication en fin de ligne. La station de communication en fin de ligne évalue ensuite les circonstances de propagation en utilisant l'UW, et effectue un décodage préalable.
