Performance Analysis of Peak-to-Average Power Ratio (PAPR) Reduction Techniques in an OFDM System

2012 Third International Conference on Computer and Communication Technology, 2012
Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for wireless transmission due to its robustness against multipath fading. However, it has some limitations such as the Peak-to-average power ratio (PAPR), which restricts its use. It reduces the efficiency of the system.

Peak-to-Average Power Ratio (PAPR) Reduction Method using Hybrid Codeword Shifting (CSC+CVMT) in an F-OFDM System

Journal of Advanced Research in Applied Sciences and Engineering Technology, 2023
One of the potential technologies for a future wireless network is filtered-OFDM (F-OFDM). The capacity to handle numerous asynchronous sub-band transmissions is necessary in order to accommodate the diversity of services. However, multicarrier transmission systems with multiple subcarriers transmit signals with high Peak-to-Average Power Ratios (PAPR).

Peak-to-Average Power Ratio (PAPR) Reduction by Pulse Shaping Using the K-Exponential Filter

IEICE Transactions on Communications, 2010
A K-exponential filter is derived and utilized for pulse shaping to reduce peak to average power ratio (PAPR) without intersymbol interference (ISI). While keeping the same bandwidth, the frequency responses of the filters vary with different values of the parameter k.

Peak to Average Power Ratio (PAPR) reduction in OFDM for a WLAN network using SLM technique

2011 3rd International Conference on Electronics Computer Technology, 2011
Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. OFDM modulation schemes offer many advantages for multicarrier transmission at high data rates over time dispersive channels, particularly in mobile applications.

Reducing peak to average power ratio (PAPR) for visible light communications (VLC) system using Walsh–Hadamard precoded discrete Hartley transforms

Journal of Optical Communications, 2022
Abstract In visible light communication (VLC), intensity modulation with direct detection (IM/DD) based on DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM) is used to transfer data at a high rate. Because OFDM signals are modulated using IM/DD, the peak of the transmitted signals is scaled up, resulting in a high ...

Peak to Average Power Ratio (PAPR) Mitigation for Underwater Acoustic OFDM System by Using an Efficient Hybridization Technique

2020 IEEE 6th International Conference on Computer and Communications (ICCC), 2020
Peak to average power ratio (PAPR) deemed as a stumbling block degrades the performance of orthogonal frequency division multiplexing (OFDM) in the underwater acoustic system by causing various issues like saturation, nonlinear distortion, and superposition of the signal spectrum within the high-power amplifier(HPA).

Peak-to-Average Power Ratio (PAPR) Reduction Using Combination of Precoding and Companding Techniques for VLC OFDM Systems

2019 TEQIP III Sponsored International Conference on Microwave Integrated Circuits, Photonics and Wireless Networks (IMICPW), 2019
In VLC system, increase in data rate leads to inter symbol interference (ISI). It is desired to reduce the high ISI using suitable modulation technique for high rate data traffic. Orthogonal frequency division multiplexing (OFDM) is an efficient modulation format to alleviate ISI effect.
