文摘The 3GPP multimedia broadcast/multicast services(MBMS) standard takes Raptor codes as a way of channel coding and puts forward an efcient enhanced Gaussian elimination(EGE) for the Raptor decoder. However, the standard decoding method is not the most efcient. 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 syn- thetic way outperforms any other ways.
