Project Title

Slicing of transfer frames



Document Number

to be assigned


5.02 Space Link Coding and Synchronization Working Group

Document Type


Description of Document

The purpose of the proposed work is to create a new book that documents transfer frames slicing in one place, such that it can be adopted in combination with synchronization and coding books (CCSDS 131.0-B, 131.2-B, 131.3-B, and 142.0-B). The new Blue Book will document an optional slicer that allows decoupling of the transfer frame length from the codeword/codeblock length, and replaces the transfer frame interface specifications in CCSDS 131.0-B, 131.2-B, 131.3-B, and 142.0-B. This will be done by using the same slicing strategy that was adopted in CCSDS 131.0-B for LDPC encoding of a stream of synch-marked transfer frames (SMTFs).
