A method and apparatus for generating a preamble sequence in an orthogonal frequency division multiplexing (OFDM) communication system having m subcarriers in a frequency domain. The method comprises generating a preamble sequence of length n that is mapped to n subcarriers on a one-to-one basis, where n is less than m; and assigning components constituting the preamble sequence to the n subcarriers among the m subcarriers on a one-to-one mapping basis, assigning null data to the remaining subcarriers excluding the n subcarriers from the m subcarriers, and then IFFT (Inverse Fast Fourier Transform)-transforming the assigned result into time-domain data.

Cette invention concerne un procédé et un appareil permettant de générer une séquence préambule dans un système de communication à multiplexage par répartition orthogonale de la fréquence (MROF) comprenant m sous-porteuses dans un domaine fréquentiel. Ce procédé consiste à générer une séquence préambule de longueur n qui est appliquée en n sous-porteuses de manière injective, n étant inférieur à m ; et à attribuer les composants constituant la séquence préambule aux n sous-porteuses parmi les m sous-porteuses au moyen d'une application injective ; à attribuer les données nulles aux sous-porteuses restantes en excluant les n sous-porteuses des m sous-porteuses ; puis à transformer par transformation de Fourier rapide inverse (IFFT) le résultat attribué en données de domaine temporel.
