Peak To Average Power Ratio (PAPR) Reduction Technique Using Selective Mapping in OFDM System

INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT
OFDM is an excellent, interference-free multicarrier modulation technique that is very efficient with the available spectrum. When practical power amplifiers are employed at the transmitter, the high peak to average power ratio (PAPR) of OFDM systems causes power inefficiency and signal distortion, which is a significant disadvantage. A distortion-free

Deep Learning Integration in PAPR Reduction in 5G Filter Bank Multicarrier Systems [PDF]

Iranian Journal of Electrical and Electronic Engineering
High peak-to-average power ratio (PAPR) has been a major drawback of Filter bank Multicarrier (FBMC) in the 5G system. This research aims to calculate the PAPR reduction associated with the FBMC system.

Companding transform technique combined with iterative filtering for reducing PAPR of OFDM signals

Tongxin xuebao, 2015
Considering the drawbacks of the traditional companding transforms，an efficient companding scheme combined with iterative filtering was proposed to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals.
