For multi-tone interference in orthogonal frequency division multiplexing (OFDM) system, one scheme is proposed, which first increases frequency domain resolution of multi-tone interference identification, and then performs parameter estimation, reconstruction and elimination on several single-tone interference one by one based on iterative computation. In multi-tone interference identification stage, ZoomFFT technology is used to improve the frequency domain resolution and simplify the computational complexity. However, down sampling sequence number after ZoomFFT does not meet the n power of 2. For single-tone interference parameters estimation, the classical maximum likelihood parameter estimation based on DFT (DFT-MLE) can be used. But when the number of sampling points is too large, DFT operation will bring great implementation complexity. Based on DFT-MLE, this paper presents an FFT based single-tone parameters estimation FFT-MLE. It not only reduces the computational complexity, but also provides better robustness on estimation performance compared with DFT-MLE. The simulation results show that this multi-tone interference cancellation scheme is effective.
