CA 2730717

The present invention provides a transmitter including a plurality of transmitting antennas, a processor for creating data symbols, and an SC- FDMA (single carrier frequency division multiple access) signal generator for taking, as an input, the data symbols, and generating SC-FDMA symbols to be transmitted through the plurality of transmitting antennas. The SC-FDMA signal generator performs an IFFT (Inverse Fast Fourier Transform) independently of each of the plurality of transmitting antennas, and each of the plurality of transmitting antennas is associated with the plurality of carriers, respectively.

La présente invention concerne un émetteur comportant une pluralité dantennes de transmission, un processeur permettant de créer des symboles de données, et un générateur de signaux SC-FDMA pour prélever, sous forme dune entrée, les symboles de données, et générer des symboles SC-FDMA à transmettre via la pluralité dantennes de transmission. Le générateur de signaux SC-FDMA effectue une transformée de Fourier inverse rapide indépendamment de chacune de la pluralité dantennes de transmission, et chacune de la pluralité dantennes de transmission est associée à la pluralité de porteuses, respectivement.
