Abstract

The invention discloses a data processing method and a data processing device. The data processing method comprises the steps of dividing data received by a receiver into first path data and second path data, acquiring burst packet starting point information and a transient frequency offset estimation value of the first path data, determining starting point information of the second path data according to the burst packet starting point information, carrying out transient frequency offset compensation on the second path data according to the starting point information of the data and the transient frequency offset estimation value, carrying out dispersion equalization processing on the second path after transient frequency offset compensation, and carrying out a subsequent data recovery operation on the second path data after dispersion equalization processing. The data processing method disclosed by the invention solves a problem of power frequency offset transient effects brought about by laser switching in related technologies, eliminates mutual effects among different DSP algorithms, compensates great line width and the frequency offset transient effects brought about by laser switching, and improves the channel utilization ratio of an optical burst coherent reception system.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data processing method and device. Background technique [0002] In recent years, high-speed coherent optical communication technology has become one of the key technologies to realize long-distance and large-capacity information transmission. By adopting technologies such as polarization multiplexing and wavelength division multiplexing, coherent optical communication technology can effectively improve system frequency band utilization and increase system capacity; High link budget. These advantages make high-speed coherent optical communication technology have broad application prospects in optical communication systems under burst mode. [0003] In a high-speed coherent optical communication system operating in burst mode, the different time-varying effects of fiber channels cause each burst packet to suffer different link impairments in the fiber link. For example, in ...
