Design of a Novel Frequency Domain Equalizer for OFDM Systems

摘要：

This paper proposes a novel frequency domain equalizer (FEQ) to eliminate inter-symbol interference (ISI) and inter-carrier interference (ICI) in orthogonal frequency division multiplexing (OFDM) systems. This FEQ employs the minimum mean square error (MMSE) criterion for getting an optimum FEQ structure based on minimizing interference. Simulation results show that the equalizer is capable of eliminating ISI and ICI effectively, and suppressing noise simultaneously.
