Simple feed-forward wide-range frequency offset estimator for optical coherent receivers

Simple feed-forward wide-range frequency offset estimator for optical coherent receivers

We propose and experimentally demonstrate a simple, feed-forward, wide-range frequency offset estimator. This frequency offset estimator is robust to spectrum asymmetry caused by electrical and optical filtering of the signal.
