Nous proposons un schéma de contrôle de puissance de sous-canal dans le système OFDM, qui transmet des données avec un niveau de puissance variable pour chaque sous-canal en fonction du SNR reçu. Le système OFDM, employant la modulation D-QPSK et le contrôle de puissance de sous-canal proposé avec un coefficient de regroupement égal à 3, donne un gain d'environ 2.3 dB en Eb/N0 comparaison avec le système OFDM conventionnel, sous le canal multitrajets à deux rayons avec la valeur moyenne du coefficient d'atténuation du deuxième rayon égale à 0.25, pour le BER requis égal à 10-5.

Abstract: We propose a subchannel power control scheme in the OFDM system, which transmits data with a variable power level for each subchannel based on the received SNR. The OFDM system, employing the D-QPSK modulation and the proposed subchannel power control with a grouping coefficient equal to 3, gives about 2.3 dB gain in Eb/N0 comparing with the conventional OFDM system, under the two-ray multipath channel with the mean value of the second-ray's attenuation coefficient equal to 0.25, for the required BER equal to 10-5.
