Adaptive Tone Reservation for better BER Performance in a Frequency Selective Fading Channel [PDF]

open access: yes, 2016
International audienceMulticarrier modulation systems suffer from large peak-to-average power ratio (PAPR). Tone reservation is a popular technique for PAPR reduction.

Particle Swarm Optimization-based dummy sub-carriers insertion for peak to average power ratio reduction in OFDM systems

open access: yesICT express, 2021
Orthogonal Frequency Division Multiplexing (OFDM) is the best choice for wireless and wired high data rate communications. The OFDM system has many advantages such as high spectral efficiency, robustness to channel fading, and immunity to impulse ...

An intelligent genetic algorithm for PAPR reduction in a multi-carrier CDMA wireless system [PDF]

open access: yes, 2008
— A novel intelligent genetic algorithm (GA), called Minimum Distance guided GA (MDGA) is proposed for peak-average-power ratio (PAPR) reduction based on partial transmit sequence (PTS) scheme in a synchronous Multi-Carrier Code Division Multiple Access (

Analysis of GFDM as a robust 5G communication technique in noisy environment [PDF]

open access: yes, 2020
One of the challenges of modulation techniques used in Fifth-Generation (5G) is their robustness in noisy environment. Conventional Orthogonal Frequency Division Multiplexing (OFDM) cannot be considered as a 5G waveform in its original form because of ...

A Novel Hybrid Precoding-Companding Technique for Peak-to-Average Power Ratio Reduction in 5G and beyond

open access: yesItalian National Conference on Sensors, 2021
Several high-speed wireless systems use Orthogonal Frequency Division Multiplexing (OFDM) due to its advantages. 5G has adopted OFDM and is expected to be considered beyond 5G (B5G).

Frequency-Selective PAPR Reduction for OFDM [PDF]

open access: yes, 2019
We study the peak-to-average power ratio (PAPR) problem in orthogonal frequency-division multiplexing (OFDM) systems. In conventional clipping and filtering based PAPR reduction techniques, clipping noise is allowed to spread over the whole active ...

Peak shrinking and interpolating for PAPR reduction in M-IFoF-based mobile fronthaul

open access: yesDigital Communications and Networks, 2022
We apply a Peak Shrinking and Interpolating (PSI) scheme to improve the Peak-to-Average Power Ratio (PAPR) performance in Multiple Intermediate-Frequency-over-Fiber (M-IFoF) based mobile fronthaul.

Power savings analysis of clipping and filtering method in OFDM systems [PDF]

open access: yes, 2008
The clipping and filtering method is analyzed in terms of power savings. The analysis takes account of the gain in the amplifier efficiency due to peak-to-average-power-ratio (PAPR) reduction.

Peak-to-average power ratio of good codes for Gaussian channel [PDF]

open access: yes, 2014
Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength.

PAPR reduction in LTE network using both peak windowing and clipping techniques

open access: yesJournal of Electrical Systems and Information Technology, 2019
Multicarrier technique orthogonal frequency division multiplexing (OFDM) modulation is a solution to provide high-speed and secured data transmission requirement in 4G technologies. Peak-to-average power ratio (PAPR) is one major drawback in OFDM system.
