Cette étude propose une méthode de réduction du rapport de puissance crête à moyenne (PAPR) utilisant un filtre adaptatif à réponse impulsionnelle finie (FIR) dans les systèmes de multiplexage par répartition orthogonale de la fréquence. Au niveau de l'émetteur, un algorithme itératif qui minimise le p-la norme d'un vecteur de signal transmis est utilisée pour mettre à jour les coefficients de poids du filtre FIR afin de réduire le PAPR. Au niveau du récepteur, le filtre FIR utilisé au niveau de l'émetteur est estimé à l'aide de symboles pilotes et son effet peut être compensé en utilisant un égaliseur pour une démodulation appropriée. Les résultats de simulation montrent que la méthode proposée est supérieure aux méthodes conventionnelles en termes de réduction du PAPR et de complexité de calcul. Cela montre également que la méthode proposée présente un compromis entre la réduction du PAPR et les performances du taux d'erreur binaire.

Abstract: This study proposes a Peak-to-Average Power Ratio (PAPR) reduction method using an adaptive Finite Impulse Response (FIR) filter in Orthogonal Frequency Division Multiplexing systems. At the transmitter, an iterative algorithm that minimizes the p-norm of a transmitted signal vector is used to update the weight coefficients of the FIR filter to reduce PAPR. At the receiver, the FIR filter used at the transmitter is estimated using pilot symbols, and its effect can be compensated for by using an equalizer for proper demodulation. Simulation results show that the proposed method is superior to conventional methods in terms of the PAPR reduction and computational complexity. It also shows that the proposed method has a trade-off between PAPR reduction and bit error rate performance.
