[Eeglablist] information regarding the signal enhancement methods

[Rajyalakshmi Matta]

dear all,

I studied the methods on signal enhancement methods. most of authors stated
that Independent Component Analysis is the best method for removal of
artifacts.

Even it is also have some limitations like it is not suitable in under
determined case ( where no of sources less than no of variables to be
found) and also it is not applicable to situations where less no.of
electrodes are used for signal capturing.

Some of them used Principal Component Analysis, common spatial pattern.

And for filtering adaptive filters, spatial filters and butter worth
filters for signal enhancement. most of them used adaptive filters/ spatial
filters.

I want to know which one is best filter and why it is best?
Is there any other process which will best fits to the EEG signal in
improving its signal -to-noise ratio
Any one please help.

thanks in advance.
