FPGA Implementation for OFDM Equalizer in High Mobile Environment

The orthogonality between subcarriers in OFDM system was destroied in high mobility of the terminals,which produced itercarrier interference(ICI) and caused severe performance degradations,an appropriate equalization technology is used to compensate the ICI.A low complexity minimum mean squared error(MMSE) equalizer for OFDM systems is implemented by FPGA,in order to ensure the effectiveness and real-time communication requirements.Verilog language is used to write program in the ISE software platform,and it is verified by Xilinx's Virtex-2 experiment board(XC2V930 chip).
