Summery-Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation technique which divides the available spectrum into many carriers. The actual and next communication schemes tend to use OFDM systems in order to provide high baud rates and less inter symbol interference. Some examples are IEEE802.11 standard, IEEE802.16 standard, MCCDMA, Digital Video Broadcasting, Wireless USB. FPGAs could support many of its operations. The main advantage of OFDM is their robustness to channel fading in wireless environment. The objective of this paper is to design and implement a base band OFDM transmitter and receiver on FPGA hardware. All modules are designed using VHDL programming language. Input and output data is displayed to computer and the results is compared using Matlab software.
