【摘要】:為了改善常用濾波器設計方法存在的不足,用一組正弦基函數(shù)神經(jīng)網(wǎng)絡線性組合逼近理想濾波器的振幅響應,用狀態(tài)轉移算法優(yōu)化基函數(shù)神經(jīng)網(wǎng)絡權值,使得實際濾波器的幅度響應逼近理想濾波器的幅度響應,建立了基于狀態(tài)轉移算法的正弦基函數(shù)神經(jīng)網(wǎng)絡濾波器設計模型。與窗函數(shù)法設計的濾波器對比,上述模型具有更好的性能,實驗結果表明,狀態(tài)轉移算法優(yōu)化權值的方法,克服了傳統(tǒng)基函數(shù)神經(jīng)網(wǎng)絡模型權值不易確定,收斂速度慢等缺點。
[Abstract]:In order to improve the shortcomings of the common filter design methods, a group of sinusoidal basis function neural networks are used to approximate the amplitude response of the ideal filter, and the state transfer algorithm is used to optimize the weight of the basis function neural network. The amplitude response of the actual filter approximates the amplitude response of the ideal filter. A sinusoidal basis function neural network filter design model based on the state transfer algorithm is established, which is compared with the filter designed by the window function method. The experimental results show that the state transfer algorithm can optimize the weights of the model, which overcomes the disadvantages of the traditional basis function neural network model, such as the difficulty to determine the weights and the slow convergence speed.
