Multichannel adaptive filter for noise and/or interference cancellation |
摘要 |
A signal processing method comprises: a) detecting sample auxiliary signals from an auxiliary signal and sample reference signals from a reference signal at different times; b) applying an auxiliary weight from a set of auxiliary weights to a corresponding sample auxiliary signal to create weighted sample auxiliary signals; c) applying a reference weight from a set of reference weights to a corresponding sample reference signal to create weighted sample reference signals; d) creating a summation value that represents the sum of the weighted sample auxiliary signals and the weighted sample reference signals; e) creating an error signal that represents the difference between the desired signal and the summation value; f) scaling the error signal to generate an update function; g) detecting the error signal; h) applying the update function to each of the auxiliary weights and reference weights; and i) returning to step (a).
