Resumen
We propose and experimentally demonstrate a hardwareefficient, feed-forward, wide-range frequency offset estimator for DSP-based optical coherent receivers. Using a simple relationship of signal spectrum, this estimator is capable to estimate offsets in a range compliant with OIF requirements. Obtained results show that this estimator has a high tolerance to spectrum asymmetry caused by electrical and optical signal filtering, even when using return-to-zero pulse shaping. © 2011 Optical Society of America. 19 26 B323 B328 Savory, S.J., Digital filters for coherent optical receivers (2008) Optics Express, 16 (2), pp. 804-817. , http://www.opticsexpress.org/DirectPDFAccess/AFC827F1-BDB9-137E- CB01717D730E3A2F_148803.pdf?da=1&id=148803&seq=0&CFID= 18083196&CFTOKEN=98368810, DOI 10.1364/OE.16.000804 Savory, S.J., Digital coherent optical receivers: Algorithms and subsystems (2010) IEEE J.
