Abstract

This paper presents the design and implementation of Orthogonal Frequency Division Multiplexing(OFDM) transmitter and receiver on Field Programmable Gate Array(FPGA). Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation technique which divides the available spectrum into many carriers.The bit error ratio with Quadrature Amplitude Modulation for OFDM using Matlab7.8.0® simulation is presented. Bit Error Ratio(BER) performance varies between 10 ֿ⁰˙² to 10 ⁰˙³.The OFDM system is synthesized using Verilog HDL and Modelsim 6.2C.Implementation is done using Xilinx Spartan 3an FPGA board.

Keywords: OFDM, FPGA, BER Simulation, Verilog HDL,Modelsim6.2C

Article published in the Proceedings of National Conference on ‘Women in Science & Engineering’ (NCWSE 2013), SDMCET Dharwad
