摘要

提出了一种经典的自适应滤波方法来解决瞬时盲信号分离问题。这种经典形式使自然梯度算法易于理解。利用这一经典解释,开发了一种新的基于rls的算法。与自然梯度算法相比,该算法在不需要预白化的情况下,在相同的稳态误差下提供了更快的在线分离速度

A Classical Adaptive Filtering Blind Signal Separation
A classical adaptive filtering view of the problem of instantaneous blind signal separation is presented. This classical form enables an easy understanding of the natural gradient algorithm. A new RLS-based algorithm is developed using this classical interpretation. The algorithm provides improved on-line separation speed under the same steady state error compared to the natural gradient algorithm without requiring pre-whitening
