Comparison of Companding based PAPR Techniques for OFDM Systems [PDF]
International Journal of Computer Applications, 2013 LTE has utilized the OFDMA for the downlink which provides spectrum flexibility, inherent resistance to Inter symbol Interference (ISI) and many more. However 3GPP LTE systems suffer from a very common problem known as Peak to Average Power ratio. The present paper tried to discuss the companding based techniques for single user OFDMA systems.

The Journal of Engineering, Volume 2019, Issue 5, Page 3460-3468, May 2019., 2019 Partial transmit sequence (PTS) is one of the effective techniques for reducing the peak‐to‐average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. PTS technique has some issues such as higher computational complexity due to its exhaustive searching of optimal phase factors.

Journal of Computer Networks and Communications, Volume 2019, Issue 1, 2019., 2019 Orthogonal frequency division multiplexing (OFDM) is the highly spectrally well‐organized method that has the difficulty of excessive peak power to average power ratio (PAPR), which ultimately imposes constraints on the high‐power amplifier. Many practices have been projected to lessen PAPR of the OFDM systems.

Advances in Condensed Matter Physics, Volume 2018, Issue 1, 2018., 2018 Light‐emitting diode‐ (LED‐) based visible light communication (VLC) has become a potential candidate for next generation high‐speed indoor wireless communication. Due to the limited modulation bandwidth of the LED, orthogonal frequency division multiplexing (OFDM) modulation is particularly preferred in the VLC system to overcome the ISI, which ...

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers
