摘要
将多个随机变量的实现的每个分量分别用相应随机变量的分布函数变换 ,再将值域空间划分为均匀格栅 ,则格栅中被占据的格子数目的期望当这些随机变量相互独立时最大。本文发现了这一有趣的规律 ,对其作出了理论解释 ,并据此提出了一种简单的盲源分离方法。该方法能够分离各种源信号且易于用数字硬件实现。
Each coordinate of the realizations of several random variables (RVs) by the distribution function of the corresponding RV and partition the range space is transformed into a uniform grid. This expected number of occupied grid-boxes will be greatest when these RVs are independent. This paper finds this interesting rule, gives a theoretical explanations, and proposes a simple method for blind source separation (BSS). This new method can separate various kinds of signals and it is in favor of digital implementation.
