System for the rapid convergence of an adaptive filter in the generation of a time variant signal for cancellation of a primary signal. |
摘要 |
<p>System for generating a secondary signal (ys(k)) for suppression of a primary signal (yp(k)), comprising: means (8) for generating a reference signal ( phi (k)): a control unit (1) having a digital filter for providing a cancellation control signal (s(k)); cancellation-generating means (2) for generating a secondary signal (ys(k)); sensor means (4) for providing an error signal ( epsilon (k)), update means (5) for providing an update signal (up(k)); an adaptation unit (7) for supplying a filtered-x signal (r(k)) to the update means (5); means for updating filter coefficients ( theta c,v(k)) of the filter in the control unit (1) with the aid of the so-called "projection algorithm" and the various features being such that an input correlation matrix defined according to equation 17 has an eigenvalue distribution which has a value which is at least substantially identical to 1 after as few steps as possible. <IMAGE></p> |
