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, we study the problem of blind deconvolution in general non-minimum phase system. Based on the second-order and fourth-order cumulants, we define a new concept of normalized cumulant to form normalized cumulant Blind blind deconvolution. A new blind equalization algorithm is derived. The computer simulation verifies the algorithm and obtains the available results.
