Abstract

Orthogonal frequency division multiplexing (OFDM) is a promising technique for fourth-generation (4G) broadband wireless communication systems. However, it suffers from inter-carrier interference (ICI) due to its sensitivity to the frequency offset caused by Doppler frequency drift. In this paper, we investigate the self-cancellation techniques to mitigate ICI for OFDM systems and a novel ICI self-cancellation scheme is proposed to mitigate the ICI effects. The performances of ICI self-cancellation schemes are analyzed in terms of the carrier-to-interference ratio (CIR) and bit error rate (BER). Simulation results demonstrate that the proposed ICI self-cancellation scheme outperforms other existing self-cancellation methods and robustness to large frequency offset.
