Deep Q-learning based optimization of VLC systems with dynamic time-division multiplexing
(IEEE, 2020)
The traditional method to solve nondeterministic-polynomial-time (NP)-hard optimization problems is to apply meta-heuristic algorithms. In contrast, Deep Q Learning (DQL) uses memory of experience and deep neural network ...
Deep reinforcement based power allocation for the max-min optimization in non-orthogonal multiple access
(IEEE, 2020)
NOMA is a radio access technique that multiplexes several users over the frequency resource and provides high throughput and fairness among different users. The maximization of the minimum the data-rate, also known as ...
Joint bit and power loading for adaptive MIMO OFDM VLC systems
(Wiley, 2020-07)
Visible light communication (VLC) is a short-range wireless access technology based on the dual use of illumination structure. The frequency-selective characteristics of VLC channels motivate the use of orthogonal frequency ...
Finite-SNR diversity gain analysis of FSO systems over gamma-gamma fading channels with pointing errors
(IEEE, 2021-06)
Free space optical (FSO) communication systems are subject to turbulence-induced fading as a result of fluctuations in the refractive index. Gamma-Gamma (GG) distribution is commonly used in the literature to characterize ...
Visible light communication for connected vehicles: How to achieve the omnidirectional coverage?
(IEEE, 2021)
Visible light communication (VLC) is based on the idea of modulating the light intensity of LEDs to transmit information and enables the dual use of exterior automotive and road side infrastructure lighting for both ...
Composite fading model for aerial MIMO FSO links in the presence of atmospheric turbulence and pointing errors
(IEEE, 2021-06)
In this letter, we introduce accurate approximation expressions for composite fading channel model and outage probability of multiple-input multiple-output (MIMO) free space optical (FSO) link between two unmanned aerial ...
SLIPT for underwater visible light communications: Performance analysis and optimization
(IEEE, 2021-10)
In this paper, we investigate simultaneous lightwave information and power transfer (SLIPT) for underwater visible light communication systems. We consider three SLIPT methods namely time switching (TS), power splitting ...
