  • This paper investigated the impact of the timing error on the receiver BER performance in the pre-equalization OFDM systems through simulations. The results showed that the timing error would bring on the phase rotation of demodulation data, and degrade the system performance critically. So it must be revised by assistant methods. The timing error and the number of sub-carriers together decide the degradation. Simulations showed that the performance would fall down 1 dB every' 1/16 normalized timing error.

Abstract: This paper investigated the impact of the timing error on the receiver BER performance in the pre-equalization OFDM systems through simulations. The results showed that the timing error would bring on the phase rotation of demodulation data, and degrade the system performance critically. So it must be revised by assistant methods. The timing error and the number of sub-carriers together decide the degradation. Simulations showed that the performance would fall down 1 dB every' 1/16 normalized timing error.
