摘要 喷泉码是一种新颖的基于图的纠删码技术,在工程应用上有广阔的前景。本文针对几种典型分布数字喷泉码的编码方式进行综合比较和规律总结,同时对喷泉码的两类译码方式和适用范围进行了分析与探讨,通过仿真数据和图形比较了不同分布编码方式的性能差异和不同译码方式的优缺点所在。 Fountain code is a novel erasure correcting code based on graph,and has a broad prospect on project application.This paper compares several kind of fountain codes with different encode degree distribution,and analysis two kinds of decode scheme.The performance of fountain codec is confirmed by simulation data and graphs.
