The 3GPP multimedia broadcast/multicast services (MBMS) standard takes Raptor codes as a way
of channel coding and puts forward an efficient enhanced Gaussian elimination (EGE) for the Raptor decoder.
However, the standard decoding method is not the most efficient. A few of researchers made some changes based
on the standard decoding method and achieved considerable performance. In this paper, a synthetic decoding
method is presented according to the existing enhanced decoding method and the simulation shows that the synthetic
way outperforms any other ways.
