Abstract :
In this paper, we present an accurate blind method for chromatic dispersion estimation in coherent optical receivers. The method is independent on modulation formats and signal spectra. Additionally, the estimation method is proven to be robust against sampling phase, polarization mode dispersion, carrier phase and frequency offset, and clock frequency offset. Excellent performance is demonstrated even in extremely bandlimited systems, so-called faster than Nyquist systems.
