ABSTRACT:
A method for controlling an identification point for binarization processing in an optical signal receiver which can diminish a code error rate by optimally tracking an identification point at all times in accordance with a received signal, thereby maintaining transmission quality high. The method comprises identification point electrical signal increment/decrement steps. When the number of error correction operations is determined to have reached a target value in a target value arrival determination step, an identification point electrical signal is left unchanged. In contrast, when the number of error correction operations is determined not to have reached the target value, the identification point electrical signal is incremented or decremented within a predetermined increment/decrement range such that the number of error correction operations approaches the target value.
