Abstract

The orthogonal frequency division multiplexing system is  a form of multicarrier modulation technology.FFT/IFFT processor is one of the key components in the implementation of wideband OFDM systems.It performs multi carrier modulation & demodulation.High performance &High speed algorithms are necessary for modulation&demodulation in OFDM transmitter &receiver respectively.

            In this paper,principles of OFDM are described  & we can implement high throughput OFDM tranceiver using efficient FFT algorithm.The processor is based on DITradix-2 FFT algorithm.Area,power dissipation &speed are most important factors when it comes to implementation of such system in VLSI domain.OFDM is used today in wireless local area network  as specified by IEEE802.11a &also used  for wireless digital radio &television  signal transmissions.
