中文摘要：
对光正交频分复用（0FDM）系统中传统导频的帧同步误差估计算法与性能进行了深入研究，针对其不足提出一种基于块状导频的由帧同步错误引入的信号幅度和相位畸变估计的新算法。仿真结果表明，在同一导频开销的条件下，对比传统块状导频与梳状导频的补偿算法，所提出的新进算法对应误码率（BER）曲线更接近无同步错误的理想BER曲线，在相同BER下，与理想曲线的信噪比（SNR）相差最大不超过0．2dB。所以，本文新算法能有效地提升性能，实现较为理想的帧同步错误的导频补偿，更适合用于纠正由帧同步误差引入的幅度和相位误差。
英文摘要：
The algorithms and performances of the frame synchronization error estimation based on the traditional pilot arrangement in optical orthogonal frequency division multiplexing （OFDM） systems are thoroughly analyzed and studied. According to their disadvantages, a new algorithm based on block-type pilot arrangement of estimating the signal amplitude and phase distortion caused by the frame synchroni- zation error is proposed. The simulation results show that under the condition of the same pilot over heads,the corresponding bit error rate（BER） performance curve of the proposed algorithm, compared with the traditional, block-type and comb-type pilot arrangement compensation algorithm,is closer to the ideal BER curve without the synchronization error, and its maximum difference of signal noise ratio （SNR） compared with that of the ideal BER curve is not more than 0.2 dB. Therefore, the algorithm can effectively improve the performance, achieve the more ideal pilot compensation performance for the frame synchronization error and is more suitable for correcting the amplitude and phase errors caused by the frame synchronization error.
