Weba linear time block code, like an LDPC code, Raptor Codes provide marvelous encoding and decoding speeds while providing near optimal performance for the BEC [8]. Raptor codes are an extension of the other part of LT codes combined with a system of pre-coding. The design and degree distribution pre-coding is the heart of Raptor codes.
