Abstract

The embodiment of the invention provides a signal impairment compensation method, a signal impairment compensation device and an optical receiver. The method comprises the following steps of: in a training mode, inputting a training sequence signal into a neural network and training the neural network by using the training sequence signal so as to acquire a weight needed by the neural network in the compensation mode; and in the compensation mode, compensating a transmitted effective data signal by using the neural network according to the weight acquired in the training mode. In embodiment of the invention, signal impairment compensation can be performed without the changing of a network structure, a scheme structure is simple, and adaptive capability is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a signal damage compensation method, device and optical receiver. Background technique [0002] With the popularity of high-speed Internet and the vigorous development of multimedia services, people have higher requirements for the bandwidth and transmission rate of Ethernet. From the initial 2.5G to 10G, and then from 10G to 40G. At present, the 10G system is still the mainstream transmission rate standard, but the coexistence of 40G and 10G, and the trend of replacing 10G is irreversible. 40G has already started commercial use in many countries and regions. However, people's requirements for bandwidth can be said to be endless, and the research on 100G has become a hot spot at present. Many people in the industry believe that 100G will achieve considerable development and commercialization in the next five years. The carrier of these high-speed communications can only be optical fi...
