Estimating Transfer Functions Based on Wavelet Transform
-
摘要: 基于离散小波变换,提出分段频带逼近,估计传递函数.首先应用分解/综合滤波器, 引进离散小波变换,然后利用小波分频性能,给出分段频带逼近算法.Abstract: Band-wise approximation based on wavelet transform is proposed for estimating transfer functions. Firstly, discrete wavelet transform is introduced by applying analysis/synthesis filter bank. Then, band-wise approximation algorithm is presented by using wavelet frequency localized quality. Simulation results have verified the proposed algorithm.
