Visible light communication system-on-chip design

In this paper, we report a System-on-Chip (SoC) architecture for OFDM-based Visible Light Communication (VLC). The OFDM block was implemented as VLC PHY layer. The OFDM block comprises of transmitter and receiver. In transmitter block, there are Reed-Solomon encoder, modulator, IFFT, and preamble generator. While in receiver block, there are Reed-Solomon decoder, demodulator, FFT, and synchronizer. In SoC, these blocks are designed as IP cores. The industry standard AXI4-Stream protocol was used for data exchange between IP cores. The OFDM model in SoC was verified by comparing with a MATLAB simulation.

Visible light communication is the future of the globe communication having applications in trust areas like V2V communication, Vehicle to infrastructure, medical domain etc., We propose a design for a computer architecture in data acquisition system using system on chip to transmit the image data and the same is received in the receiver side. The proposed mode consist of hardware and software task.The hardware task is designed using zybo board which is soc board and Xilinx is used as an interface between hardware and the system. The proposed mechanism proves to have better data acquisition capability than other models at a higher data rate

<p class="0abstract">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 <em>baud rate</em> has bandwidth up to 921600 bps.</p>
