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 ...
Incremental diversity order for characterization of FSO communication systems over lognormal fading channels
(IEEE, 2020-04)
Free space optical (FSO) communication systems experience atmospheric turbulence-induced fading, which is typically modelled by lognormal distribution. Since the decreasing rate of error probability over lognormal fading ...
Asymptotic performance of generalized transmit laser selection over lognormal turbulence channels
(IEEE, 2020-08)
In free space optical communication systems, transmit laser selection (TLS) has been proposed as an efficient fading-mitigation technique over turbulence channels. In TLS, the transmitter is equipped with a number of laser ...
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 ...
Experimental investigation of lens combinations on the performance of vehicular VLC
(IEEE, 2020)
With the increasing adoption of LEDs in outdoor light sources such as traffic lights, street lights and vehicle headlamps, visible light communication (VLC) has the promise to become a major enabler for vehicle-to-vehicle ...
Vehicle-to-infrastructure visible light communications: Channel modelling and capacity calculations
(IEEE, 2020)
In this paper, we investigate the performance of a visible light communication (VLC) system for vehicle-to-infrastructure (V2I) connectivity. Two headlamps of the vehicle serve as wireless transmitters while photodetectors ...
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 ...
