| 1. | Meanwhile , we also study the convergence behavior of iterative detection in different methods , which are the proposed average source entropy and the covariance matrix perturbation characterized by the variations of its dominant eigenvalue as well as the conventional approach based on the mutual information 为了分析迭代译码的收敛特性,本文从不同角度出发,在研究了传统的互信息方法的基础上,本文首次提出并使用了平均信源熵和用协方差矩阵最大特征值表征其抖动这两种方法,使迭代过程的收敛分析变得简单方便。 |
