摘　　要：本文以文献[4]为基础,研究了一般的非最小相位系统的盲解卷积问题,提出了一个基于二阶、四阶累积量的归一化累积量概念,形成一个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。Based on [4], this paper consider the general blind deconvolution problem of nonmini- mum systems,a new concept of normalized cumulant consisted of second-and fourth cumulants is proposed,and a new blind deconvolution criteria of normalized cumulant matchins is presented, then a new algorithm is derived,and computer simulation results are included to demonstrate the performance of the proposed algorithm.

关 键 词：盲解卷积 盲均衡 累积量 码间干扰
