description The present invention discloses the structure and operation of the "geometric shift transform" that enables the use of symbol alphabet code word representation of a user's binary data stream as the signal transport format from a central unit (modem) of a precoded OFDM system to a remote unit (the RF equipment). The invention simplifies the precoding transform (DFT) calculation, enables secure transmissions, and contemplates layer and resource block mapping operations in the central unit. La présente invention concerne la structure et le fonctionnement de la « transformée de décalage géométrique » qui permet l'utilisation d'une représentation de mot de code alphabétique de symbole du flux de données binaires d'un utilisateur en tant que format de transport de signal d'une unité centrale (modem) d'un système OFDM précodé à une unité distante (l'équipement RF). L'invention simplifie le calcul de transformée de précodage (DFT), permet des transmissions sécurisées, et envisage des opérations de mappage de couche et de bloc de ressources dans l'unité centrale.
