| 摘 要： | 提出一种适用于非线性自适应除噪（ANC）的神经网络方法。当参考通道中的噪声是主通道噪声的非线性变换时，采用线性ANC往往效果不好，此时应采用非线性ANC。由于径向基函数网络具有良好的非线性函数逼近性能，因而可采用基于径向基函数网络的非线性自适应除噪。模拟结果表明，这种方法具有明显的抑制噪声能力。

| Abstract: | This paper presents a kind of neural networks method which is suitable for nonlinearANC While the reference noise is the nonlinear transform of the primary noise, the effect ofANC is usually poor if linear ANC is applied. In this case, nonlinear ANC shou1d be used. SinceRBFN's good performance in approximating nonlinear function, nonlinear ANC bascd on RBFNcan be used. Simulaton results show that the metnod can greatly reduce noisc. |
