Abstract
A circuit comprises a decision unit configured to obtain a plurality of decision errors based on a demodulated signal and an original symbol; a calculator configured to calculate an instant direct current error based on the plurality of the decision errors, and first and second variance error signals based on the instant direct current error; an error detector configured to obtain a first result by determining whether an absolute value of both the first variance error signal and an the second variance error signal are larger than a first threshold; obtain a second result by determining whether an absolute value of a first decision error of the plurality of the decision error is larger than a second threshold; and output a second closest constellation point as a corrected symbol corresponding to the first decision error at least based on the first result and the second result.
