摘要

本文利用三阶和四阶积累量研究了瞬时混叠信号盲分离的问题──根据源信号通过瞬时叠加后的观测值恢复出源信号．我们提出的判据指出：对独立的源信号，若其中高斯信号不超过一个，则源信号能够得到恢复．基于判据，我们提出了两种分离算法．模拟实验证实了其有效性．

Abstract

We have studied the problem of blind source separation of instantaneous mix tures

which is to recover the unknown sources from observations without knowing the characteris tics of the transmission medium

by using third─and fourth─order cumulants.A class of criteria are presented

which state that for independent sources

it is sufficient for separation that there is no more than one Gaussian.lgorithms are also developed based on these criteria

whose efficiency is verified by experiments.
