ABSTRACT

In this paper, an effective design and implementation of the Multi-user orthogonal frequency division multiplexing based orthogonal chaotic vector shift keying (Multi-User OFDM-OCVSK) system over multipath fading channel by using field programmable gate array (FPGA) platform is presented. The system model is designed and implemented using Xilinx system generator (XSG) tool with Vivado 2019.1 software. The Xilinx System Generator (XSG) is used because it is more reliable, flexible, easy to update and modify the system design in addition to give the perfect design for FPGA technique compared with the traditional FPGA design. The VHDL code file is generated and the hardware co-simulation of the suggested system is performed on the Kintex 7 KC705 evaluation kit. The system is routed in successfully using Vivado 2019.1 program with 100 MHZ clock frequency. The results of hardware simulation prove that the system is worked in the correct form in real time process.
