# Adaptive noise cancelling: Principles and applications

@article{Widrow1975AdaptiveNC, title={Adaptive noise cancelling: Principles and applications}, author={Bernard Widrow and John R. Glover and John M. McCool and John Kaunitz and C. Williams and R H Hearn and James R. Zeidler and Jr. Eugene Dong and Ryan Goodlin}, journal={Proceedings of the IEEE}, year={1975}, volume={63}, pages={1692-1716} }

This paper describes the concept of adaptive noise cancelling, an alternative method of estimating signals corrupted by additive noise or interference. [...] Key Method The method uses a "primary" input containing the corrupted signal and a "reference" input containing noise correlated in some unknown way with the primary noise. The reference input is adaptively filtered and subtracted from the primary input to obtain the signal estimate. Expand
