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
在基於矢量矩陣的結構化方法中，通過對矢量矩陣進行一系列特殊處理可以構造出稀疏的『 0 』 、 『 1 』校驗矩陣，而校驗矩陣中的雙對角結構易於構造出相應的ldpc碼字，模擬表明，採用矢量矩陣的結構化方法具有和-旋轉構造法相當的性能，但是實現的復雜度大於-旋轉構造法，同時碼率和碼長受到一定的限制，這也是未來需要研究的方向。 -
