FPGA Implementation of Short Frame OFDM System for Sensors Networks

Abstract

This paper focus on the physical layer of a new communication protocol using Orthogonal Frequency Division Multiplexing (OFDM), and its implementation on FPGA mock-up for pressure and temperature sensors application. We implement the design of the OFDM transmitter and receiver blocks. We present an aeronautic sensors application in which a Power Line Communication (PLC) for sensors networks based on OFDM is implemented on FPGA. We show a laboratory test between FPGA connected to several pressure and temperature sensors; and a computer displaying a graphical user interface (GUI).
