| 摘 要： | 将高阶统计量与盲分离的移位阻断SHIBBS算法相结合, 利用高阶统计量能辨识非最小相位系统和SHIBBS算法分离效果与计算量适中的特点, 提出一种在频域内对MIMO系统进行辨识的方法； 针对在此解混后的信号存在排序不确定性的问题, 直接在频域上采用互四阶累计量, 从而很好地对信号进行了分离； 针对信号的比例模糊问题, 利用LMS自适应的恒模算法（CMA）对排序后信号均衡补偿, 仿真实验证明了此算法的有效性.

| Abstract: | Based on the combination of higher order statistics that can identify non-minimum phase system with shift block method of blind separation(SHIBBS) algorithm which is good in separation and moderate amount of computation,an algorithm was proposed to identify the multi-input and multi-output(MIMO) system in frequency domain;but the received signals are uncertain in permutation,which is solved by means of cross fourth-order statistics and the signals are separated well.To the problem of scale ambiguity,the con... |
