Systems and methods are provided for transmitting OFDM information via IFFT up- sampling components that transmit data at a higher sampling rate than conventional systems to simplify filter requirements and mitigate leakage between symbols. In one embodiment, an NL point IFFT is performed on a zero inserted set of frequency domain symbols. Ih another embodiment, the NL point IFFT is further optimized by exploiting the fact that (N-I) L of the frequency domain symbols are zero. This enables an embodiment that consists of a pre- processor that multiplies the input samples by complex phase factors, followed by L point IFFTs.

L'invention concerne des systèmes et des procédés destinées à la transmission d'informations OFDM par l'intermédiaire de composants de sur-échantillonnage (IFFT) qui transmettent des données avec une fréquence d'échantillonnage plus élevée que les systèmes conventionnels pour simplifier les exigences de filtrage et atténuer les fuites entre les symboles. Dans un mode de réalisation, une IFFT sur NL points est réalisée sur un ensemble d'insertion nulle de symboles de domaine de fréquence. Dans un autre mode de réalisation, la IFFT sur NL points est davantage optimisée, car (N-I) L des symboles de domaine de fréquence valent zéro. Cette caractéristique permet d'obtenir un mode de réalisation comprenant un préprocesseur qui multiplie les échantillons d'entrée par des facteurs de phases complexes, puis des IFFT sur L points.
