英文摘要	In this paper, we propose a wide-range LFO estimation and correction procedure for a coherent optical FBMC/OQAM system. Using a deliberately designed preamble, this method can not only precisely estimate the fractional frequency offset, but also effectively implement the estimation of the integer frequency offset. After a correction of the frequency offset, the final channel responses are acquired by inter-frame averaging and cubic spline interpolation. We investigated the accuracy and stability of this method under the influence of fiber dispersion and nonlinearity. The results from numerical simulation experiments show that the proposed low complexity technique is fully applicable to fiber channel and can significantly improve the performance of CO-FBMC/OQAM systems with respect to the bit-error-rate. © 2019 SPIE.
