A space-time-frequency block coding apparatus and method in a transmitter with three transmit (Tx) antennas are provided. An input symbol sequence is transmitted through three Tx antennas according to a permutation method using a selected transmission matrix. A pre-coder pre-codes a symbol vector of the input symbol sequence to output pre-coded symbols. A space-time-frequency block code (STFBC) mapper selects an STFBC using a permutation matrix, maps the pre-coded symbols to the transmit antennas according to the selected STFBC, and transmits the mapped symbols through the transmit antennas. This can be useful in improving the performance of an STFBC.
L'invention concerne un dispositif de codage de bloc espace-temps-fréquence et un procédé correspondant mis en oeuvre dans un transmetteur comportant trois antennes de transmission (Tx). Une séquence de symboles d'entrée est transmise par l'intermédiaire des trois antennes de transmission selon un procédé de permutation faisant intervenir une matrice de transmission sélectionnée de manière à améliorer les performances d'un code de bloc espace-temps-fréquence (STFBC).
