Performance of multicarrier cooperative communication systems over underwater acoustic channels
(IET Communications, 2017)
Multicarrier transmission in the form of orthogonal frequency division multiplexing (OFDM) is an efficient method to handle inter-symbol interference resulting from the frequency selectivity of the underwater acoustic (UWA) ...
Optical MIMO-OFDM with generalized LED index modulation
(IEEE, 2017-08)
Visible light communications (VLC) is a promising and uncharted new technology for the next generation of wireless communication systems. This paper proposes a novel generalized light emitting diode (LED) index modulation ...
A mobile channel model for vlc and application to adaptive system design
(IEEE, 2017-05)
In this letter, we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing, we first obtain channel impulse responses for each point over the user ...
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 ...
On the performance of NCC-OFDMA systems in the presence of carrier frequency offset
(IEEE, 2017)
Network coded cooperative (NCC) systems have recently gained increasing attention due to their high power and spectral efficiency. For high speed data transmission over frequency-selective channels, NCC is further combined ...
Poster: on-board camera video transmission over vehicular VLC
(IEEE, 2017)
Vehicular connectivity is envisaged to extend vehicle on-board camera videos to the nearby vehicles in order to increase drivers' road awareness. This paper demonstrates the possibilities of video transmission captured by ...
Finite-SNR diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(IEEE, 2017-03)
Network-coded cooperation (NCC) is an effective method to improve the throughput efficiency in cooperative wireless networks. The combined use of orthogonal frequency division multiplexing (OFDM) with NCC has been further ...
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 analysis of relay-assisted NLOS ultraviolet communications over turbulence channels
(IEEE, 2017)
Ultraviolet (UV) communication enables non-line-of-sight (NLOS) outdoor wireless connectivity and is particularly desirable for relaxing or eliminating pointing and tracking requirements of infrared links. In the current ...
IEEE 802.15.7r1 reference channel models for visible light communications
(IEEE, 2017)
The IEEE has established the standardization group 802.15.7r1 “Short Range Optical Wireless Communications”, which is currently in the process of developing a standard for visible light communication (VLC). As with any ...
