The present invention relates to a filter bank approach to adaptive filtering
method using independent component analysis. More particularly, the invention relates
to a method of improving the performance of adaptive filtering method by applying
independent component analysis that is capable of reflecting the secondary or even
higher order statistical characteristics to adaptive filtering algorithm using
the filter bank approach.
In order to implement the conventional adaptive filter algorithm using independent
component analysis to the real world problem, a large number of filter training
coefficients are required and also a large amount of calculation is required when
a training is undertaken. This results in a very slow learning speed and the deterioration
in the quality of result signals.
The adaptive filtering method using independent component analysis according
to the present invention provides a method of reducing the large amount of calculation
required for filter training, improving the learning speed and the quality of result
signals by utilizing a filter bank approach.
Hence, the filter bank approach to adaptive filtering method using independent
component analysis according to the present invention is capable of improving the
performance over the conventional adaptive filtering method using independent component analysis.
