This paper analyzes the performance of a block implementation frequency domain adaptive algorithm, and from its result, derives a convergence condition as the range of step size. The validity of the convergence condition is verified by computer simulation.
In this paper, we propose a method for repeatedly updating the coefficients of the feedback control filter used for canceling a feedback path from a loudspeaker to a noise detection microphone. The coefficients are usually estimated by feeding a sequence of extra noise to the loudspeaker. However, feeding such extra noise under active noise control is… (More)
