Implementation of LT Code with a Novel Degree Distribution

摘要：

　　It is known that Luby Transform code (LT code) is the first code fully realizing the digital fountain concept and provides an efficient scheme to transfer information over different channels.The key to make LT code work well is the degree distribution used in the encoding procedure.It determines the degree of each encoding symbol.On the basis of robust solition distribution and optimized degree distribution,a novel degree distribution which has only one parameter is proposed in this paper.Through computer simulation,the performance of LT code with the novel degree distribution is better than the robust solition distribution and sparse degree distribution.The conclusion of the research is practically valuable in improving the efficience of data distribution application.
