Huh. That's slightly disappointing.
Do you know of any other fountain codes more powerful than the LT code described in the article, that are not particularly patent encumbered? This seems like a really interesting area, but from reading around a bit, it seems like part of the issue is that because all of the research is so recent, you end up stepping on someone or other's IP.
- mpoloton 8y agoYou can have a look at Tornado codes[1]. These codes are also based on LT codes and their patent seems to be no longer in effect. For a completely open and free alternative for application-level forward erasure correction (AL-FEC) codes, checkout OpenFEC[2]. 1 - https://en.wikipedia.org/wiki/Tornado_code https://en.wikipedia.org/wiki/Tornado_code 2 - http://openfec.org http://openfec.org
- mpoloton 8y agoOnline Codes (https://en.wikipedia.org/wiki/Online_codes https://en.wikipedia.org/wiki/Online_codes) are very similar to Raptor codes for rateless erasure coding. The construction consists of an inner an outer code. However unlike RaptorQ, they are not optimized for an entire range of block lengths.
