Hybrid VLC/WiFi Architectures with Priority Feedback Channels
2022 61st FITCE International Congress Future Telecommunications: Infrastructure and Sustainability (FITCE), 2022In this paper, we consider integrating Visible Light Communication (VLC) and WiFi technologies in an ultra-dense (massive) Internet of Things scenario, where WiFi links are used for complementing VLC links and vice-versa. Indeed, in case of mobility and/or bidirectional communications, limited coverage areas and self-generated interference can be an ...

A New Architectural Approach to VLC Application
SSRN Electronic Journal, 2020During the last decade, the exponential growth of mobile devices and wireless services created an enormous demand for radio frequency-based technologies. Meanwhile, the industry has been revolutionized thanks to the popularization of LED light bulbs, which are more economical and efficient. In that context, light communication (VLC) may be a disruptive

Improved Architectures for VLC MAP decoders
2006 3rd International Symposium on Wireless Communication Systems, 2006This paper describes a methodology for designing MAP-based VLCs, which have been demonstrated to outperform classic VLC approaches in terms of BER performance, although it can be applied to any MAP-based scheme. The architecture presented is based on differential metrics, which allow area savings of up to 40% without losses in BER or FER performance ...

Heterogeneous Wi-Fi and VLC (RF-optical) wireless access architecture
2015 23rd International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2015Visible light communication (VLC) is rapidly emerging as a compelling technology for supplementing traditional radio frequency communication, enabling energy-efficient data transmission and offering high downlink speeds. On the other side, traditional Wi-Fi radio access can be used as an uplink solution.

SVD-VLC: A novel capacity maximizing VLC MIMO system architecture under illumination constraints
2013 IEEE Globecom Workshops (GC Wkshps), 2013Multiple-input multiple-output (MIMO) systems using multiple light emitting diode (LED) sources and photodiode (PD) detectors are attractive for visible light communication (VLC) as they offer a capacity gain proportional to the number of parallel single-input single-output (SISO) channels.

An Efficient VLC Encoder Architecture for H.264
2006 International Symposium on Intelligent Signal Processing and Communications, 2006Variable length coding (VLC) is a widely used technique for data compression. Exp-Golomb VLC is adopted for entropy coding in H.264, the latest developed video coding standard. In this paper, we propose an efficient architecture of Exp-Golomb VLC encoder in which the codewords can be constructed by using the modified coding number technique. It results

A Multi-Element VLC Architecture for High Spatial Reuse
Proceedings of the 2nd International Workshop on Visible Light Communications Systems, 2015Visible light communication (VLC) is an emerging wireless technology that offers more capacity than legacy radio frequency (RF) communications can offer. Free-space-optical (FSO) communication is VLC's general form spanning infrared bands, and it has an upper hand on traditional RF systems due to license-free spectrum, containment of beams, inherent ...

Adaptive learning architecture-based predistorter for nonlinear VLC system
Photonic Network Communications, 2019A light-emitting diode (LED) acts as a transmitter in a visible-light communication (VLC) system. However, the nonlinear characteristics of LED limit the performance of the VLC system by degrading the quality of a transmitted signal. In recent years, several forms of predistorters have been proposed to mitigate the effects of LED nonlinearity; however,
