- dredmorbius 3y agoThere are some papers discussing this, e.g.: "Polar Coding for Forward Error Correction in Space Communications with LDPC Comparisons", Naveed Namipour, Haleh Safavi, & Harry Shaw. <https://ntrs.nasa.gov/api/citations/20190032244/downloads/20190032244.pdf https://ntrs.nasa.gov/api/citations/20190032244/downloads/20...> Also "Design of Low-Density Parity-Check (LDPC) Codes for Deep-Space Applications" <https://ipnpr.jpl.nasa.gov/progress_report/42-159/159K.pdf https://ipnpr.jpl.nasa.gov/progress_report/42-159/159K.pdf> The first specifically discusses early missions.
