A lightgbm equalization system and method for improvement of imdd short-distance optical communication system

Abstract

The invention discloses an improved Lightgbm equalization system for IMDD short-distance optical communication system, comprising: an optical transmitting module, an optical receiving module, a gradient descent tree equalizing module, and a data output module; The high-speed optical signal is sent to the optical receiving module; the optical receiving module converts the received optical signal into an electrical signal corresponding to the optical signal, and the optical receiving module samples the electrical signal to obtain the training sequence and valid The feature vector of the data, and input the obtained training sequence and the feature vector of the valid data into the gradient descent tree equalization module; the gradient descent tree equalization module will receive the training sequence and the data sample of the feature vector of the valid data. The predicted value of the data sample is obtained through the learner, and the balanced information data is obtained; the balanced information data is output through the data output module to realize the reception of user data.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an improved Lightgbm equalization system and method for IMDD short-distance optical communication systems. Background technique [0002] In recent years, with the rise of future applications such as cloud computing, unmanned driving, virtual reality, and online games, both industrial and commercial circles have put forward higher requirements for optical access networks and short-distance communications. Unlike long-distance networks, its large end users have high cost sensitivity. Therefore, maintaining high capacity while maintaining low cost has become the focus of these system designs. How to effectively realize low-cost, high-speed short-distance optical transmission has become a research hotspot in the field of optical communication, especially in the field of data center optical interconnection. A simple and effective way is to use low-bandwidth optical dev...
