The CCSDS (The Consultative Committee for Space Data Systems) published an “experimental specification” for near-earth and deep space communication in 2007. The document was contributed to CCSDS by NASA (National Aeronautics and Space Administration). In 2011 the LDPC codes were adopted by a blue book as “recommended standard”.
The documents describe ten LDPC codes, one optimized for near-earth communication (block length 8176), and all others optimized for deep space communication. The block lengths of the deep space codes were selected such that three lengths of information words exist (1024, 4096, and 16384).
