| Abstract: | Stability has been a major concern in the designing of adaptive active noise control earphone and the precison of the error path model directly determine the stability of the system. In this paper, we introduce a new adaptive modeling structure based on our knowledge of the characteristics of feed forward adaptive active noise control earphone.The proposed structure distinguishes itself from classical ones by its capability of obtaining higher modeling precision under heavy interference. |
