Orthogonal Frequency Division Multiplexing (OFDM) is a Frequency Division Multiplexing (FDM) technique used as a digital multi-carrier modulation method. A large number of closely spaced sub carriers which are orthogonal are used to carry data on several parallel data streams. OFDM uses the spectrum efficiently compared to Frequency Division Multiple Access (FDMA) by spacing the channels much closer and creating all the carriers orthogonal to one another. Orthogonality of the carriers prevents interference between the closely spaced carriers and provides high bandwidth efficiency. This work focuses on design and implementation of OFDM transmitter and receiver. Corresponding blocks of OFDM transmitter and receiver includes Quadrature
