摘要: Carrier phase estimation techniques are provided for processing a received optical signal having carrier modulated according to modulation scheme. First and second operations performed on digital derived from an obtained the using coherent reception. The first operation tracks relatively fast variations of produce slow estimation. A difference between estimations is computed. Occurrence cycle slip determined when greater than threshold. correction applied low pass filtered exceeds
