Update TM channel coding Blue Book with LDPC Codes


Document Number



5.02 Space Link Coding and Synchronization Working Group

Document Type


Description of Document

Objective of this project is to add the LDPC Codes to the TM channel coding blue book (131.0-B).
This project has been created splitting into 3 projects the original task of adding three new codes with the following areas of applicability :
- LDPCC, applicable to science missions
- SCCC, applicable to Earth Exploration Satellites (EES) Missions for data rates above 100 Mbaud
- DVB-S2 code, applicable to EES Missions for data rates up to 150 Mbaud

Applicable Patents

There are patent issues in this work area, but appropriate ISO forms have been submitted indicating RAND licensing policy by the patent holder or licensor (explain in comments).

Patent Comments

LDPC Codes patents are applicable to the new added part. ISO form signed. Turbo Codes patents are applicable to the old unmodified part.
