Abstract:
When a frequency deviation compensation amount is compensated for by use of frequency shift, a phase offset occurs between adjacent input blocks included in a plurality of input blocks as divided, with the result that an error occurs in a reconstructed bit sequence. A frequency deviation compensation system of the invention is characterized by comprising: a frequency deviation compensation means for compensating for a frequency deviation occurring in a signal by use of frequency shift; and a phase offset compensation means for compensating for a phase offset occurring, in the signal, due to the frequency shift.

Claim (Index 18):
The digital coherent optical receiver according to  claim 13 , further comprising a frequency deviation estimator configured to estimate the frequency deviation,\n wherein when the frequency deviation compensation amount compensated by the frequency deviation compensator is dynamically changed, the frequency deviation estimator is further configured to output a frequency deviation estimated value to the compensation amount calculator.
