A cross-correlation is calculated between a multi-bit digital signal derived from the optical signal and a known symbol sequence of the SYNC burst. The cross-correlation is logically partitioned into sub-blocks. A candidate sub-block in which the SYCN burs is mot likely located is identified, and analysed to estimate a location of the SYNC burst."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal framing in a coherent optical receiver","description":"A method and system for a estimating a most likely location of a periodic SYNC burst within an optical signal received through an optical communications system.
