Abstract-Visible Light Communication (VLC) is an emerging optical communication technology with rapid development nowadays. VLC is considered as a compliment and successor of radio-frequency (RF) wireless communication. There are various typical implementations of VLC in which one of them is for exchanging data TCP/IP packets, thus the user can browse the internet as in established Wireless fidelity (Wi-Fi) technology. Briefly, we can call it by Light fidelity (Li-Fi). This paper described the design and implementation of System-on-Chip (SoC) subsystem for Li-Fi application where the implemented SoC consists of hardware (H/W) and software (S/W). In the H/W aspect, Physical Layer (PHY) is made by using UART communication with Ethernet connection to communicate with Host/Device personal-computer (PC). In the S/W aspect, Xillinux operating system (OS) is used. The H/W-as well as S/W-SoC, are realized in FPGA Zybo Zynq-7000 EPP development board. The functional test result shows (without optical channel or Zybo-to-Zybo only) that the implemented SoC is working as expected. It is able to exchange TCP/IP packets between two PCs. Moreover, Ethernet connection has bandwidth up to 83.6 Mbps and PHY layer baud rate has bandwidth up to 921600 bps.

“…For future 40Gb/s and 100Gb/s wireless access, new VLC network architecture with the backbone of fiber link is urgent demand. We proposed a novel ultra high-speed LED VLC local area network to support massive users in a huge office building based on star topology architecture [6]. Figure 1 shows the star topology architecture of VLC network.…”

“…The VLC technology is mostly based around the intensity modulation of white light emitting diodes (LEDs) (in-organic [8] and organic [9]), which can be switched on and off at a very high rate [10], thus enabling data communications, illuminations, sensing as well as indoor localization [11]. LEDs are widely used in everyday infrastructures including homes, offices, street and traffic lights and smartphones [12]. In display devices such as smartphones or computers, the individual elements of the pixel arrays can be independently modulated [9] and captured with a camera (i.e., optical camera communications) in order to recover the transmitted information [13].…”

Abstract-The paper proposes a novel camera-based receiver for visible light communications for a short range mobile-tomobile communications link. The receiver captures data from the screen of a transmitting smartphone and uses the speeded up robust features algorithm to effectively detect it. The receiver performs a projective transformation to accurately eliminate perspective distortions caused by the displacement of the devices. The paper also introduces a quantization process in order to suppress the inter-symbol interference resulting from the dynamic nature of the environment. A range of experiments are carried out in order to evaluate the system performance when the position parameters are varied. We show that the proposed system is capable of achieving a very high success rate of 98% in recovering the transmitted images under test conditions.
