Adaptive DCO-OFDM for underwater visible light communications
(IEEE, 2019-04)
Visible light communication (VLC) has been introduced as a complementary technology to acoustic communications for underwater applications. Underwater VLC can achieve much higher data rates sufficiently high for real-time ...
Channel modeling and performance characterization of underwater visible light communications
(IEEE, 2018-07-03)
Underwater visible light communication (UVLC) has emerged as an attractive complementary solution to long-range acoustic communication and is able to achieve much higher data speeds. In this paper, we investigate the ...
Performance characterization of vertical underwater VLC links in the presence of turbulence
(IEEE, 2018-09-24)
In this paper, we investigate the performance of vertical underwater visible light communication (VLC) links. In vertical links, water properties such as temperature and salinity change with the depth. This leads to changes ...
Effect of eddy diffusivity ratio on underwater optical scintillation index
(The Optical Society, 2017-10-11)
The performance of underwater optical wireless communication systems is severely affected by the turbulence that occurs due to the fluctuations in the index of refraction. Most previous studies assume a simplifying, yet ...
Adaptive OFDM-based acoustic underwater transmission: system design and experimental verification
(IEEE, 2017)
In this paper, we present the design and implementation of a software defined orthogonal frequency division multiplexing (OFDM)-based underwater acoustic (UWA) communication system with link adaptation. Our system ...
Performance characterization of underwater visible light communication
(IEEE, 2019-01)
In this paper, we investigate the performance limits of underwater visible light communication (UVLC) systems. We first develop a closed-form path loss expression as a function of transceiver parameters and water type. We ...
Diversity gain analysis of underwater vertical MIMO VLC links in the presence of turbulence
(IEEE, 2019)
To satisfy the demands of high data rate underwater applications such as image and real-time video transmission, underwater visible light communication (UVLC) has emerged as an alternative to acoustic signaling. One of the ...
Vertical underwater VLC links over cascaded gamma-gamma turbulence channels with pointing errors
(IEEE, 2019)
Underwater visible light communication (UVLC) is a high capacity wireless connectivity solution with low latency, particularly appealing for real-time underwater video and image transmission. While attenuation and geometrical ...
FPGA based DCO-OFDM PHY transceiver for VLC systems
(IEEE, 2019)
Satisfying the demand for high bandwidth and low latency in Visible Light Communication (VLC) systems is a difficult challenge. VLC channels exhibit frequency-selectiveness at peak-speeds. This phenomenon generates a serious ...
Transmit laser selection for underwater visible light communication systems
(IEEE, 2019)
Visible light communication (VLC) has the potential to serve as a high-speed underwater wireless connectivity solution to support real-time image and video transmission. Underwater propagation medium imposes additional ...
