Apparatus and method for automatically debugging parameter of communication system

Abstract

The invention provides a device and a method for automatically debugging parameters of a communications system. The device comprises a debugging object choosing unit, an error signal obtaining unit, an error signal analyzing unit and an adjustment unit, wherein the debugging object choosing unit is used for choosing a receiver and / or a sender of the communications system to be used as an object to be debugged, and choosing the current debugging parameter of the object to be debugged; the error signal obtaining unit is used for obtaining an error signal and transmitting the error signal to the error signal analyzing unit; the error signal analyzing unit is used for analyzing the error signal and judging whether the current debugging parameter can be adjusted or not according to the analysis result, if the adjustment is needed, the adjustment information recording the adjustment direction is transmitted to the adjustment unit; the adjustment unit is used for adjusting the current debugging parameter according to the adjustment information. The invention can improve the debugging efficiency and the debugging accuracy of the parameters of the sender and the receiver of the communications system, and realize automatic debugging and accurate calibration.

Description

technical field [0001] The invention relates to the technical field of digital communication, in particular to an automatic debugging device and method for an optical communication system transmitter and receiver. Background technique [0002] In a digital communication system, the parameters of the transmitter and receiver are important factors that affect system performance. These parameters include the cross point of the transmitter's eye diagram, the driving amplitude, the Von level of the EA (electro-absorption, electrical absorption) modulated laser, Receiver decision level, APD (Avalanche Photodiode, avalanche photodiode) receiver bias, etc. The parameters of the transmitter and the parameters of the receiver influence each other. When the parameters of the transmitter change, the parameters of the receiver also need to be adjusted accordingly to ensure the best transmission performance of the system. At the same time, for different application environments, due to t...

AI Technical Summary

Problems solved by technology

[0003] The usual debugging process is to set the parameters of the transmitter and receiver to a fixed empirical value. Due to the discreteness of the device and the difference in the application environment and other factors, such a debugging method cannot guarantee that the set parameters are optimal.
