The application of adaptive filters in noise canceling
often requires the relative placement of the two transducers
at a distance that necessitates a large order filter in
order to obtain an adequate output signal-to-noise ratio.
A new adaptive filter structure is introduced that permits
a closer placement of the transducers and that allows cancellation
of noise in the presence of crosstalk. Algorithms are developed
for the new transversal and lattice filter estimators.
Simulations show considerable improvement in mean-square
error over that obtained with standard noise canceling
algorithms.
