摘要
The expression for electron count optimal threshold value has been obtained in the article, the expression for evaluation of potentially achievable average error probability value during binary signals differentiation by an optical receiver with consideration of synchronization error has been refined. It has been shown that a time interval error switches the receiver into a mode that does not provide minimal average error probability. This explains a significant increase in error probability, which is mostly caused by errors during transmissions of "zeros" due to a lowered count threshold value. The obtained results enable us to determine synchronization error exchange conditions on optical signal power with a predetermined average error probability value, and to substantiate synchronization precision tolerances.
