| Abstract: | This paper focuses on the design of the decoding algorithm for Raptor codes with minimum shift keying（MSK） modulation over additive white Gaussian noise （AWGN） channels. Based on the characteristics of Raptor codes and MSK modulation, an improved belief propagation decoding algorithm for Raptor codes is proposed. Simulation results prove that the proposed decoding algorithm has a better decoding performance. |

| Keywords: | Raptor codes factor graph AWGN channels belief propagation decoding |
