Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. The method according to claim 11, further comprising:
in response to the bit error rate threshold being used, obtaining noise amounts respectively associated with the sampled electrical signal and the ideal electrical signal;
obtaining a modification relationship between a transmitter and dispersion eye closure penalty and a noise amount based on the noise amounts that are respectively associated with the sampled electrical signal and the ideal electrical signal and that are obtained in response to the bit error rate threshold being used; and
modifying the determined transmitter and dispersion eye closure penalty TDECcalculated according to the following:

TDECactual=TDECcalculatedf(TDECactual,TDECcalculated)

wherein TDECactual represents a modified transmitter and dispersion eye closure penalty, and f(TDECactual, TDECcalculated) represents the modification relationship between a transmitter and dispersion eye closure penalty and a noise amount.
