Résumé

En utilisant les bonnes caractéristiques temporelles et fréquentielles de la forme d’onde modulante, il est possible de construire une modulation multiporteuse qui réduit les interférences d’une transmission sans fil. Dans cet article, la Wavelet Packet Modulation (WPM) est appliquée aux communications sans fil et une nouvelle modulation basée sur les ondelettes est proposée qui utilise les ondelettes complexes. Les simulations montrent que la WPM est plus performante que la modulation OFDM (Orthogonal Frequency Division Multiplexing) pour une transmission avec des interférences bande étroite importantes. Pour une transmission à travers un canal multi-trajets, l’utilisation des ondelettes complexes permet d’améliorer l’utilisation des ondelettes réelles et elle est plus performante que la modulation OFDM lorsque le préfixe cyclique n’est pas employé.

Abstract

Based on the good time-frequency characteristics of the pulse shaping, it is possible to build a multicarrier modulation that reduces wireless interferences. In this paper, the Wavelet Packet Modulation (WPM) is applied to wireless communications and a new wavelet based multicarrier modulation is proposed which used complex wavelets. Simulations show that WPM outperforms the useful OFDM (Orthogonal Frequency Division Multiplexing) modulation for a transmission with strong narrowband interferences. For a multipath channel transmission, the use of complex wavelet outperforms the use of the real one and outperforms OFDM modulation when the cyclic prefix is not used.
