On Raptor Codes
Hossein Pishro-Nik, Faramarz Fekri · 2006 IEEE International Conference on Communications · 2006
We introduce a construction of raptor codes to be used over symmetric channels. An important property of the proposed scheme is that unlike the previous construction of raptor codes, it allows to design codes that are approaching the capacity of the underlying channel in a rate-compatible way. We also show that for finite-length codes, the proposed construction outperforms the previous constructions of raptor codes.
