摘要 针对现有的基于矩阵的最小冗余再生码的构造方法中存在的编码和重构复杂度高及参数选择受到限制的问题,设计了一种矩阵实现的最小冗余再生码的构造方法.该方法通过改变数据矩阵和修复向量的结构,能够有效地减少最小冗余再生码的编码和数据重构的复杂度,同时参数的选择更加简单和灵活. This paper designed a novel product-matrix minimum storage regenerating( PM-MSR) codes which can efficiently reduce the encoding and reconstructing complexity by modifying the structure of data matrices and repairing vectors. For the proposed PM_MSR codes,the parameters are more simple and the construction is more flexible.
