METHOD, DEVICE AND SYSTEM FOR SIGNAL PROCESSING BASED ON SINGLE CARRIER-FREQUENCY DOMAIN EQUALIZATION(SC-FDE)

摘要

A signal processing method based on single carrier-frequency domain equalization(SC-FDE), includes: an optical transmitter generating unique words(UW) sequence and a synchronous data block, providing a data frame with the unique words sequence, generating a superframe by the synchronous data block and the data frame, and transmitting the superframe as a base-band signal to an optical receiver. A signal processing system is based on SC-FDE. Said solution enable simplifying a process of an optical transmitter hardware device, reducing manufacturing cost of the optical transmitter, improving accuracy of time synchronization and reducing processing resources of channel estimation.
