Efficient, Non-Data-Aided Chromatic Dispersion Estimation via Generalized, FFT-Based Sweep

We propose a method that eliminates the 2 samples/symbol requirement on FFT-based CD estimation, and generalizes this highly-efficient, non-data-aided, frequency-domain CD estimation approach to systems with η samples/symbol where 1<η ≤ 2.
