Implementation of Orthogonal Frequency Division Multiplexing with FPGA

<p>In recent years, there have been dramatic shifts in cellular and telecommunication industries. As smartphones are dominating on the cellphone market, more and more people use these mobile devices to access internet either through third generation network or IEEE802.11 wireless local area network. Orthogonal frequency division multiplexing (OFDM) has been widely used in IEEE802.11 wireless local area network and fourth generation network. This paper will focus on the design and implementation of an Orthogonal Frequency Division Multiplexing system on field-programmable gate array (FPGA). The major components of an OFDM system include a modulator, an N-input inverse Fast Fourier Transform (IFFT), two root raised cosine filters (RRC filter), an N-input Fast Fourier Transform (FFT), and a demodulator. These components are designed by using very-high-speed integrated circuits (VHSIC) hardware description language (VHDL) under development environment of ModelSim, and then implemented onto Altera cyclone II EP2C35F672C6. The FFT accuracy is measured by comparing outputs from ModelSim to Matlab. The performance of the developed OFDM is evaluated in a wireless communication testbed.</p>
