This paper presents a symbol-by-symbol decoding algorithm of 3GPP MBMS Raptor. We redefine the initial matrix of 3GPP MBMS Raptor, and add some ancillary information to help make up for destruction of linear relationship in matrix caused by advanced Gauss elimination in 3GPP MBMS Raptor. So we can realize a correct decoding by symbolby- symbol, while 3GPP can not. The proposed algorithm is adapted to an erasure channel with large symbols, low code rate, big time delay or high error probability , and it can greatly improve decoding efficiency.
