一种高性能对称FIR系数的推导及其应用

A New High Performance Symmetrical FIR Coefficience and Its Application

Daubechies小波双尺度方程系数（可看作FIR滤波器）在数字情号处理领域得到了广泛的应用，这说明了小波双尺度方程系数比小波函数本身更有吸引力．本文作者试图通过经典的付氏分析理论，应用与Daubechies不同的方法，从不同的角度，推导出一种新的对称小波双尺度方程系数（可看作对称FIR滤波器），力图浅显易懂，严格合理。

The use of Daubechies scaling lertion coefficience is very wide in digtal signal processing domain.All of these fully demonstrate Daubechies scaling function coefficience is more attractive than the the wavelet itself weattempt to deduce the scaling function coefficience by using the classical Fourier analysis with the approch different from Daubechies with a new viwpoint and angle. We strive to make this derivement explicit and strict.
