Abstract/OtherAbstract:
The delayless frequency-domain implementation of least mean squares (LMS) algorithm is attractive because it can eliminate undesired block delay in the signal path while still remain the advantages of the frequency-domain LMS algorithm. However, the conventional delayless frequency-domain LMS experiences difficulties in slow convergence when it is applied to harmonic signal control at some frequencies. In this study, an overlap-save implementation of the delayless frequency-domain LMS algorithm is proposed to overcome the convergence problem mentioned above. Simulations show that the proposed implementation has better performance than the original one either in the pure tone application or in the vehicle powertrain noise application.
