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 ...
Network-coded cooperative systems with generalized user-relay selection
(IEEE, 2020-11)
We consider a network-coded cooperative (NCC) system that consists of N >= 2 sources, M >= 1 decodeand-forward (DF) relays, and a single destination. The relays perform network coding (NC) on the received sources' symbols ...
MAC layer performance of multi-hop vehicular VLC networks with CSMA/CA
(IEEE, 2020)
Majority of works in the field of vehicular visible light communication (VLC) networks are based on some ideal assumptions. Particularly, the ideal Lambertian pattern is assumed for channel modeling and only a simple ...
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 ...
Coverage of a shopping mall with flexible OLED-based visible light communications
(The Optical Society, 2020-03-30)
Visible light communications (VLC) can utilize light-emitting diodes (LEDs) to provide illumination and a safe and low-cost broadcasting network simultaneously. In the past decade, there has been a growing interest in using ...
Channel modelling and performance limits of vehicular visible light communication systems
(IEEE, 2020-07)
Visible light communication (VLC) has been proposed as an alternative or complementary technology to radio frequency vehicular communications. Front and back vehicle lights can serve as wireless transmitters making VLC a ...
Low complexity least minimum symbol error rate based post-distortion for vehicular VLC
(IEEE, 2020-10)
Vehicular visible light communications (VLC) has emerged as a viable supplement for high speed next-generation vehicle to vehicle (V2V) communication systems. However, performance of a V2V-VLC link is impaired due to ...
Unified performance analysis of multi-hop FSO systems over double generalized gamma turbulence channels with pointing errors
(IEEE, 2020-11)
Free space optical (FSO) communication systems provide high bandwidth in unregulated spectrum and act as a powerful line-of-sight wireless connectivity solution. The performance of FSO systems can be seriously impaired by ...
Delivery phase in cache-based wireless networks with modified LT codes
(Springer Nature, 2020-10)
Caching has emerged as an efficient technique to reduce delivery latency and network congestion. The focus of this paper is on content delivery in the caching-based wireless systems. In view of the fact that in such systems, ...
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 ...
