| Abstract(in English) | In this paper we consider the structure and the adaptive algorithm of the adaptive noise canceller based on the linear modeling of the signal generation part. The adaptive exponential filter that is placed at the output of the signal generation part estimates the minimum phase inverse transfer function of the generation part. The signs of the weight of the adaptive exponential filter are reversed, then they are copied into the weight of the exponential filter placed at the output of the generation part, and as a result, this exponential filter suppresses the noise. The adaptive algorithm is a gradient algorithm in which the convergence is guaranteed, and the numerical verifications of the theoretical analysis are strictly executed by the computer simulation. |
