- In this paper, we present frequency-domain implementations
of two adaptive multichannel blind deconvolution filters
that employ the independent component analysis principle.
The proposed implementations achieve considerable
computational gains, which is shown by performing detailed
analysis on the computational complexity. Particularly,
our implementations incorporate a nonholonomic constraint
to deal with overdetermined cases. The developed
algorithms were successfully applied to the blind separation
of real-world speech signals.
