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 12):
The digital coherent optical receiver according to  claim 1 , wherein the frequency deviation compensator is further configured to compensate the frequency deviation upstream of a polarization demultiplexer.
