摘　　要：以ＳＷ理论为基础，研究了一般的非最小相位系统的盲解卷积问题；基于二阶、四阶累积量，定义了一个新的概念──归一化累积量，形成了归一化累积量匹配的盲解卷积准则；并导出了一种新的盲均衡算法，计算机模拟验证了该算法，获得了可用结果。Based on SW theory , this paper studies the general blind deconvolution problems of non- minimum systems . A new concept of normalized cumulant stemmed from second and fourth order cumula- nts is defined . The normalized cumulant character of signal passing linear systems is analyzed . Then a new blind deconvolution criteria of normalized cumulant matching is presented , and a new algorithm is al- so derived . The usable computer simulation results for demonstration of the performance of the proposed algorithm are obtained .
