16.6 Gbps data rate for underwater wireless optical transmission with single laser diode achieved with discrete multi-tone and post nonlinear equalization.
TL;DR: By incorporating post nonlinear equalization with a 3rd-order diagonal plane kernel, the received signal-to-noise ratio (SNR) can be improved by ~2 dB compared with a linear equalization method.
Journal ArticleDOI
Discrete multitone transmission for underwater optical wireless communication system using probabilistic constellation shaping to approach channel capacity limit.
TL;DR: To the best of the authors' knowledge, this is the first time to employ PCS-QAM-DMT in a UOWC system, and it is also the highest data rate ever reported for a single LD in UowC.
Journal ArticleDOI
Experimental demonstration of 50-m/5-Gbps underwater optical wireless communication with low-complexity chaotic encryption
TL;DR: This is the first time to verify the feasibility of chaotic encryption in a high-speed UOWC system and the DFT-S DMT gives a better performance than the DMT scheme under different water turbidities.
Journal ArticleDOI

TL;DR: In this article , a wideband photomultiplier tube (PMT)-based underwater wireless optical communication (UWOC) system is proposed and a comprehensive experimental study of the proposed PMT-based UWOC system is conducted, in which the transmission distance, data rate, and attenuation length (AL) is pushed to 100.6 meters, 3 Gbps, and 6.62, respectively.
Journal ArticleDOI
Improving the Performance of Long Reach UOWC With Multiband DFT-Spread DMT
TL;DR: In this article, a multiband discrete Fourier transform spread (DFT-spread) scheme was proposed to reduce the peak-to-average-power ratio (PAPR) of discrete multi-tone (DMT)-based underwater optical wireless communication (UOWC) system.
