A single transmitter transmits K communication bursts in a shared spectrum in a time slot of a time division duplex communication system. The system associated with N midamble sequences. Each burst has an associated midamble sequence. A receiver receives a vector corresponding to the transmitted midamble sequences of the K communication bursts. A matrix having N identical right circulant matrix blocks is constructed based in part on the known N midamble sequences. The wireless channel between the transmitter and receiver is estimated based on in part one of the N blocks and the received vector.
Un émetteur unique transmet K rafales de communication dans un spectre commun dans une tranche horaire d'un système de communication duplex à répartition dans le temps. Le système est associé à N séquences intercalaires. Chaque rafale présente une séquence intercalaire. Un récepteur reçoit un vecteur correspondant à la séquence intercalaire transmise des K rafales de communication. Une matrice comportant N blocs de matrices de circulation de décalage à droite identiques est construite basée en partie sur les N séquences intercalaires connues. La voie sans fil entre l'émetteur et le récepteur est estimée à partir de la première partie des N blocs et le vecteur reçu.
