AI Technical Summary

Problems solved by technology

The reflection signal generated by multiple reflections finally enters the optical receiver together with the normal optical signal, which seriously affects the system performance
When the transmission intermediate node is damaged, or there are many transmission intermediate nodes, the optical signal can be deteriorated sharply due to the crosstalk of the reflected signal

Abstract

Provided are a communication device and system, and a method for processing a signal. A fixed reflection delay in a communication link and a corresponding reflection coefficient are used to eliminate reflection crosstalk caused by a reflection signal, and improve communication quality.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication device, system and signal processing method. Background technique [0002] As the communication rate continues to increase, optical communication becomes more and more popular. [0003] In optical communications, signals are carried on optical wavelengths for transmission. During the transmission process, the optical signal will be reflected in the transmission medium or at the transmission intermediate node. The reflection signal generated by this reflection phenomenon is a kind of crosstalk to the normal signal, which will affect the system performance. [0004] In fact, the optical signal may experience multiple reflections in the transmission medium or at the intermediate nodes of transmission. The reflected signal generated by multiple reflections finally enters the optical receiver together with the normal optical signal, thereby seriously ...
