With the rapid growth of digital communication in last few years, the need for high speed data transmission is increased. To support the high speed services like video, data and voice need efficient wireless systems. OFDM is a most efficient multicarrier modulation system used for achieving high data rates in mobile environment because of its multicarrier modulation technique and ability to convert a frequency selective fading channel into several nearly flat fading channels. Also, it becomes very efficient technique for data transmission over multipath fading environment due to its properties like high bandwidth efficiency and resistance to multipath fading. Also, its implementation becomes easier with the help of Fast Fourier Transform and Inverse Fast Fourier Transform for demodulation and modulation respectively.
