Abstract
Crosstalk reduction and/or cancellation systems and methods are provided herein. In exemplary embodiments, a far-end acoustic signal may be delayed by M samples. Additionally, a crosstalk estimate value for the delayed far-end acoustic signal may be subtracted from an input acoustic signal. The crosstalk estimate value is a scaled version of filter outputs generated by a finite impulse response filter that utilizes predetermined filter coefficients. The filter outputs are scaled using a dynamic gain value.
