Implementation of an Efficient OFDM transmitter and Receiver Using FPGA

Abstract

In this paper an efficient implementation of an Orthogonal Frequency Division Multiplexing (OFDM) system is proposed. Nowadays a lot of researches are going on OFDM since it is a high speed modulation technique and can be used in optical fiber communication systems. Also OFDM utilizes the available bandwidth with maximum efficiency. The proposed architecture improved the efficiency of the system by improving the error detection and correction method. The proposed method saves a considerable amount of time when an error occurs in the transmitted data and the system demands retransmission. The proposed system is simulated using Xilinx ISE 14.2 and successfully implemented on Spartan 6 FPGA.
