摘 要: | 传统BCH码串行迭代译码算法计算量大、译码速度慢,无法满足大数据环境下快速译码的要求。本文提出一种基于MapReduce分布式框架的并行译码算法,通过译码的分布式和并行化减少译码时间,通过查找表译码减少译码时的计算量,从而获得较好的译码性能。

Abstract: | Due to decoding speed of traditional BCH code serial iterative decoding algorithm is very slow,cannot meet the requirements of big data decoding of BCH.A parallel decoding algorithm based on MapReduce distributed framework is presented,this algorithm can reduce the decoding time on the distributed-parallel decoding and reduce computation by the lookup table,thus obtaining agood decoding performance. |
