Frequency based asymptotic distribution of the PAPR for geometric adding signal approach in OFDM signals context
Guel, D. and Palicot, J. and Bellanger, J.-J.
The distribution of the peak-to-average power ratio (PAPR) for Geometric method [1] of PAPR reduction in orthogonal frequency-division multiplexing (OFDM) signals is evaluated in order to analyse the influence of the carrier frequency of adding signal on the PAPR reduction. Assuming that the baseband OFDM signal is characterized as a band-limi(...)

Réduction du PAPR par Ajout de Signal hors bande dans un contexte de Signaux Multiporteuses
Désiré Guel , Jacques Palicot , Yves Louët
Dans cet article il est question de la mise en oeuvre d'une technique de réduction du rapport puissance maximale à puissance moyenne (PAPR) pour des systèmes OFDM par ajout de signal artificiel. Nous présentons une nouvelle technique de réduction du PAPR par ajout de signal pour des signaux multiporteuses, nous étudions ensuite sa complexité a(...)

A Geometric Method for PAPR Reduction in a Signal Adding Context for OFDM Signals
Desire Guel; Yves Louet; Jacques Palicot
This paper presents a new technique for OFDM signal PAPR reduction by adding an artificial signal in order to restrict the envelope of the resulting signal. The algorithm is presented, some simulation results and a complexity study are given. According to these results, the new method outperforms the conclusions presented in [1]. The PAPR is r(...)
