摘要：

Modeling loudspeaker system with the Volterra series expansion is essential to eliminate the nonlinear distortion. We have proposed a method measuring the Volterra kernel of loudspeaker system by multi sinusoidal waves. This method, however, has problems not to consider the phase property of nonlinear element and the third-order distortion. Therefore, we propose a novel method measuring the second-order Volterra kernel by multi sinusoidal waves. In this method, the phase property of nonlinear element and the third-order distortion are considered. Moreover, we offline eliminate the nonlinear distortion of loud-speaker system with the Volterra kernel measured by the novel method and show the effectiveness.
