Chromatic dispersion estimation based on complementary Golay sequences for 80 Gb/s QPSK single-carrier system with frequency domain equalization
In this paper, we present a chromatic dispersion (CD) estimation technique based on complementary Golay sequences for systems employing single-carrier with frequency domain equalization (SC-FDE) format. By exploiting the unique correlation property of Golay sequences and using the sequences as channel estimation symbol (CES), chromatic dispersion can be estimated by measuring partial phase response and compensated using frequency domain equalization (FDE) with relatively low complexity in both the training sequences and estimation algorithm. The technique is verified by computer simulation to be able to estimate and compensate for up to 1500 km fiber with standard dispersion at high accuracy in 80 Gb/s coherent NRZ-QPSK system.
