title = "Segmented frequency offset compensation algorithm in coherent optical sub-sampling system",
abstract = "An inter-partitioned FFT algorithm is proposed to estimate the difference between the frequency of local optical sampling pulse and the signal to be sampled in coherent optical sampling system. By dividing the sampled data into several parts, the frequency difference of each part is estimated using FFT, respectively. The experiment demonstrated that, with the inter-partitioned FFT algorithm, the measured Q factor of 32GB QPSK signal is improved by 6dB, and matched the results obtained by the commercially available optical signal analyzer (EXFO PSO-200).",
