vector matrix
Examples
- On the other hand , in the approach based on vector - matrix , through several special operations on vector - matrix , we have constructed a sparse ‘ 0 ’ , ‘ 1 ’ parity - check matrix with dual diagonal matrix whose structure can easily construct the code . the simulation results have demonstrated the performance of this approach is similar to that of - rotation while the complexity is also higher . this problem is to be solved in the future research
在基于矢量矩阵的结构化方法中,通过对矢量矩阵进行一系列特殊处理可以构造出稀疏的‘ 0 ’ 、 ‘ 1 ’校验矩阵,而校验矩阵中的双对角结构易于构造出相应的ldpc码字,仿真表明,采用矢量矩阵的结构化方法具有和-旋转构造法相当的性能,但是实现的复杂度大于-旋转构造法,同时码率和码长受到一定的限制,这也是未来需要研究的方向。 - This treatise has researched on the construction of structured ldpc codes , including eg , bibd , semi - random - rotation and an approach based on vector - matrix proposed by us and compared random construction and structured construction through theoretical analysis and simulation . we also compared several structured codes
