| Abstract(in English) | In this paper, we examine the accuracy of identification method using the frequency domain adaptive Volterra filter(FAVF)we proposed in actual loudspeaker systems.We have identified nonlinear systems by using the adaptive Volterra filter(AVF)modeling loudspeaker systems by the Volterra series expansion up to now.However, the AVF has a problem that the computational complexity becomes huge when the tap length is large.Hence we show the FAVF using Overlap-save method to be possible to reduce the computational complexity and the identification method introducing Volterra sampling theorem.And the effectiveness is examined in the actual loudspeaker.Moreover, we eliminate the nonlinear distortion of loudspeaker systems with the Volterra kernel identified by the FAVF on offline, and show the effectiveness of the FAVF. |
