Project Title

Update TM channel coding Blue Book with LDPC slicing



Document Number



5.02 Space Link Coding and Synchronization Working Group

Document Type


Description of Document

Objective of this project is to add LDPC slicing to the LDPC Codes relevant section(s) TM channel coding in the Blue Book (131.0-B). The feature will add a mechanism similar to the one already used for SCCC (131.2-B) and DVB-S2 (131.3-B). The change will be done via a pink sheet in the framework of the 3-years review of the 131.0-B (review relative to the LDPC portion, added to the book in 2011).
