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.

Reducing Peak-to-Average Power Ratio in OFDM Systems by adaptive dynamic range companding

, 2006
Conference PaperOne of the major drawbacks of OFDM systems is the notoriously high peak-to-average-power-ratio (PAPR). In this paper we study the performance of a novel PAPR reduction scheme proposed recently, namely Adaptive Dynamic Range Companding ...
