PHY Layer Design of OFDM-VLC System based on SoC using Reuse Methodology

A System-on-Chip (SoC) architecture for OFDM-based Visible Light Communication (VLC) system is presented in this paper. It is developed with AXI4 system bus standard, which is generally used in the SoC design. The PHY layer can be accessed by ARM Cortex-A9 processor using memory-mapped I/O method. Several peripherals such as USB, Ethernet, and SDIO are also integrated to the processor. The system can run Linux OS based on Ubuntu 16.04. The system has been implemented on Xilinx Zynq-7000 SoC platform.
