Various solutions are proposed to counterbalance a nonlinear echo by using the echo canceller, and it causes the nonlinearity when the voice from the speaker with the nonlinearity is assumed to be linear and it processes it and the performance of the echo canceller worsens. Then, it proposes the nonlinearity of the speaker and it proposes the method of improving deterioration in processing by approximating by the straight line, and doing linear processing in each section by using two or more adjustment filters. Moreover, the reduction in the computational complexity when it simulates on the computer, and this method is used is considered. |
