An Implementation of OFDM Transmitter and Receiver on Reconfigurable Platforms

Tirumala Rao Pechetty, Mohith Vemulapalli

Many of the present communication systems tend to use Orthogonal Frequency Division Multiplexing (OFDM) because of the higher data rates, low inter symbol interference (ISI) and easily compatible to the variation in the frequency. The present standards use inbuilt IP’s for the implementation of OFDM Transmitter and Receiver. This work provides the validation and implementation of OFDM Transceiver on FPGA which is completely digital, and the whole work is done using VHDL language. Field Programmable Gate Arrays provide the better platform for the variation of data rates and moreover they are of low cost, easily programmable. Software tools and hardware used in the implementation are Xilinx ISE, Modelsim, Chipscope tools and Spartan 3E FPGA
