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.

Simulation and comparative study for peak to average power ratio (PAPR) reduction techniques in OFDM for wireless communications

, 2020
Orthogonal Frequency Division Multiplexing (OFDM) is an effective method for transmission data with high speed rate. OFDM system uses orthogonal subcarrier to transfer data which make this system more efficient than multi carrier system, by exploit all the carrier frequency band.

PAPR Reduction of Complex Wavelet Packet Modulation (CWPM) System using a Novel Hybrid Technique over Selective Rayleigh Fading Channel

Journal of Engineering and Sustainable Development, 2013
High Peak to Average Power Ratio (PAPR) of transmitted signal is one of the major drawbacks of the complex wavelet packet modulation (CWPM). Utilizing the advantage of concentrating the energy to certain subspaces of the discrete wavelet transform ...
