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 ...

A New Approach to Peak Threshold Estimation for Impulsive Noise Reduction Over Power Line Fading Channels [PDF]
, 2018 Impulsive noise (IN) is a major component that degrades signal integrity in power line communication (PLC) systems. PLC systems driven by orthogonal frequency-division multiplexing (OFDM) have Rayleigh distributed amplitudes.

Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018 This study proposes an iterative, joint channel estimation, equalization, and data detection method in the presence of high mobility for a multicarrier downlink system that communicates over rapidly time‐varying channels. The proposed method uses a basis expansion method (BEM) which has low computational complexity and helps to reduce the number of ...

IET Communications, Volume 19, Issue 1, January/December 2025.This article proposes a hybrid SLM+PTS+RNN algorithm to mitigate the high PAPR challenge in UFMC systems for B5G networks. The method significantly improves power efficiency (by 30%–40%) while maintaining BER and PSD performance, outperforming traditional PAPR reduction techniques.

A PAPR correction scheme for LoRa self‐jamming waveforms
IET Communications, Volume 18, Issue 19, Page 1588-1603, December 2024.A self‐jamming scheme of LoRa waveforms enabling secure transmissions is recently proposed in literature, which performs well in simulations. However, experiments on SDR equipment immediately showed that a transmission is impossible due to PAPR introduced by the waveform modification.
