Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a communication system where multiple carriers are used to transmit the data. It is popularly used because of it is very much robust to frequency selective distorted channels. In this paper, we are focusing on the design and an implementation of OFDM transceiver on FPGA. VHDL is used in implementation of the system, high level synthesis tool is used for synthesis and it is targeted on Xilinx Spartan 3e device. ISE simulator is used to simulate presented design and the results are presented. This paper presents resources utilization for transmitter and receiver when 4 and 8 subcarriers are used. For floating point multiplication, addition subtraction and division required for design we are utilizing the Intellectual Property (IP) cores provided by Xilinx. To calculate IFFT and FFT we are using DIT radix-2 butterfly approach.
