Novel adaptive transmission algorithms for free-space optical links
(IEEE, 2012-12)
Atmospheric turbulence is a major degrading factor in free-space optical (FSO) systems. Since turbulence-induced fading results in a very slowly-varying channel, reliable feedback is possible allowing the implementation ...
Adaptive unipolar MIMO-OFDM for visible light communications
(IEEE, 2019)
Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for ...
Adaptive MIMO FSO communication systems with spatial mode switching
(IEEE, 2018-08)
In this paper, we propose an adaptive multiple-input multiple-output (MIMO) free-space optical (FSO) system with dynamic adaptation between spatial modes of operation. The proposed adaptive system supports three MIMO modes. ...
Performance of OFDM-based adaptive visible light communications
(IEEE, 2017)
In this paper, we investigate the performance of a direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) based adaptive transmission in the context of visible light communication (VLC). We ...
Link adaptation for MIMO OFDM visible light communication systems
(IEEE, 2017-11-10)
In this paper, we investigate link adaptation for an orthogonal frequency division multiplexing (OFDM)-based multiple-input multiple-output (MIMO) visible light communication (VLC) system. The proposed adaptive OFDM VLC ...
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 ...
Adaptive free space optical communication system with multiple apertures
(2016)
In the current literature on free space optical (FSO) communication, typically open-loop designs are considered where the knowledge of channel state information is only available at the receiver. This is mostly favorable ...
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 ...
An adaptive modulation scheme for coded free-space optical systems
(IEEE, 2014)
For very slowly-varying fading channels as in the case of atmospheric turbulence-induced fading, it is possible to reliably estimate the channel state information and send it back to the transmitter. The transmitter can ...
Effect of scattering phase function on underwater visible light communication channel models
(Elsevier, 2021-10)
Non-sequential ray tracing simulations are commonly employed to model underwater visible light communication (VLC) channels. The accuracy of such simulations highly depends on how well the optical properties of water (i.e., ...
