Title (EN) SELECTIVE TONE RESERVATION FOR PAPR REDUCTION IN WIRELESS COMMUNICATION SYSTEMS
(FR) RÉSERVATION DE TONALITÉ SÉLECTIVE POUR LA RÉDUCTION DE PAPR DANS DES SYSTÈMES DE COMMUNICATIONS SANS FIL
Abstract:
(EN) A method for reducing peak-to-average power ratio (PAPR) in a time domain of Orthogonal Frequency Division Multiplexing (OFDM) signal using selective tone reservation (STR) is provided. The method comprises: distributing a first PAPR reduction signal among unused resource blocks (RBs); distributing a second PAPR reduction signal among occupied RBs; applying non-iterative clipping and filtering to the OFDM signal, modified by the first PAPR reduction signal and the second PAPR reduction signal. The method is fast and has a high performance. STR fully fits in 4G/5G standard requirements and its complexity does not require a huge computational resources.
(FR) L'invention concerne un procédé de réduction du rapport de la puissance crête à la puissance moyenne (PAPR) dans un domaine temporel d'un signal à multiplexage par répartition orthogonale de la fréquence (OFDM) à l'aide d'une réservation de tonalité sélective (STR). Le procédé consiste à : distribuer un premier signal de réduction de PAPR entre des blocs de ressources (RB) inutilisés ; distribuer un second signal de réduction de PAPR entre des RB occupés ; appliquer un écrêtage et un filtrage non itératifs sur le signal OFDM, modifié par le premier signal de réduction de PAPR et le second signal de réduction de PAPR. Le procédé est rapide et très performant. La STR répond parfaitement aux exigences de la norme 4G/5G et sa complexité n'exige pas d'importantes ressources de calcul.
