A block coding apparatus and method in an OFDM mobile communication system are provided. They reduce PAPR to 3dB or less, while increasing a traditional block coding rate by twice, by use of complementary sequences. Therefore, spectral efficiency is improved by twice, maintaining the traditional error correction capability, and thus decoding is facilitated.
L'invention porte sur un appareil et sur un procédé de codage de bloc dans un système de communication mobile OFDM. On réduit à 3dB ou moins PAPR (rapport de puissance crête/moyenne) et on multiplie par deux la vitesse de codage de bloc traditionnelle au moyen de séquences complémentaires. Ceci permet de multiplier par deux le rendement spectral tout en conservant une capacité de correction d'erreur traditionnelle, et de faciliter ainsi le décodage.
