Overview
Project Title	Slicing of transfer frames
Approval	Approved
Document Number	131.0-B
Charter	5.02 Space Link Coding and Synchronization Working Group
Document Type	Blue
Description of Document	The purpose of the proposed work is to define a transfer frames slicing, such that it can be adopted in the TM synchronization and coding book (CCSDS 131.0-B) while in harmonization with other synchornization and coding books (131.2-B, 131.3-B, 431.1, and 142.0-B). The updated Blue Book will document an optional slicer that allows decoupling of the transfer frame length from the codeword/codeblock length. This will be done by using the same slicing strategy that was adopted in the same book for LDPC encoding of a stream of synch-marked transfer frames (SMTFs), that is also adopted in 131.2-B, 131.3-B, 431.1, and 142.0-B.
