This paper presents an analytical study of signal clipping that leads to the noise/distortion in the waveform of DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM)-based visible light communication (VLC) systems. The pilot-assist

In this paper, an investigation of some selected Mie and geometric Scattering models for free space optical (FSO) communication was done on available atmospheric data in Nigeria. The Kim and Kruse models have been established for the temperate region

Turbulence-induced fading is a critical performance degrading factor for underwater wireless optical communication (UWOC) systems. In this paper, we propose a quasi-cyclic (QC) low-density parity-check (LDPC) code with multiple-pulse-position modulat

In this paper, low-density parity-check (LDPC)-coded carrierless amplitude and phase (CAP) modulation with spatial diversity is proposed to mitigate turbulence-induced fading in an underwater visible-light communication (UVLC) channel. Generalized-ga

In this paper, a pilot-assisted scheme is used to reduce the peak-to-average power ratio of multicarrier signalling based visible light communication systems and the system throughput is maximised with bit and power loading.

This paper experimentally demonstrates the resilience of frequency-shift keying (FSK) signalling to turbulence effect in underwater optical wireless communications. The findings offer valuable insight into the design trade-off between spectral effici
