Dans cet article, nous proposons une nouvelle réduction du PAPR en utilisant l’hybride d’une méthode de séquences de transmission partielle (PTS) et d’une méthode de réduction adaptative de puissance de crête (APPR) avec une technique d’informations secondaires codées (SI). Ces procédés sont utilisés dans un système de multiplexage par répartition orthogonale de la fréquence (OFDM). L'OFDM utilise des sous-porteuses orthogonales pour la modulation des données. Ces sous-porteuses présentent de manière inattendue un rapport puissance crête/puissance moyenne (PAPR) élevé dans certains cas. Afin de réduire le PAPR, la séquence des données d'entrée est réorganisée par PTS. La méthode APPR est également utilisée pour contrôler le niveau de crête des signaux de modulation par un algorithme adaptatif. Une méthode de réduction proposée comprend ces deux méthodes et réalise les deux avantages en même temps. Afin de créer la condition optimale sur le PTS pour la réduction du PAPR, un coût de calcul assez important doit être exigé et il est donc impossible d'obtenir le PTS optimal. Dans la méthode proposée, en utilisant la condition pseudo-optimale avec une technique SI codée, le coût total de calcul est considérablement réduit. Dans les résultats de simulation, la méthode proposée montre l’amélioration du PAPR et révèle également les hautes performances en matière de taux d’erreur binaire (BER) d’un système OFDM.

Abstract: In this paper, we propose a new PAPR reduction by using the hybrid of a partial transmit sequences (PTS) and an adaptive peak power reduction (APPR) methods with coded side information (SI) technique. These methods are used in an Orthogonal Frequency Division Multiplexing (OFDM) system. The OFDM employs orthogonal sub-carriers for data modulation. These sub-carriers unexpectedly present a large Peak to Average Power Ratio (PAPR) in some cases. In order to reduce PAPR, the sequence of input data is rearranged by PTS. The APPR method is also used to controls the peak level of modulation signals by an adaptive algorithm. A proposed reduction method consists of these two methods and realizes both advantages at the same time. In order to make the optimum condition on PTS for PAPR reduction, a quite large calculation cost must be demanded and thus it is impossible to obtain the optimum PTS. In the proposed method, by using the pseudo-optimum condition with a coded SI technique, the total calculation cost becomes drastically reduced. In simulation results, the proposed method shows the improvement on PAPR and also reveals the high performance on bit error rate (BER) of an OFDM system.
