自适应Bernstein多项式用于一类双通道双正交小波滤波器组的设计。该滤波器组属于半带对滤波器类,并用两个核函数定义。自适应Bernstein多项式是用来构建核函数。Bernstein多项式的参数设计是通过最小二乘法实现。第一步,分解低通滤波器的设计。第二步,设计重构低通滤波器。用两阶段方法,设计过程是有效的,包括求解线性方程组。该设计方法可以方便地设计不同的特性。
Adaptive Bernstein Polynomials for a Class of Dual Channel Biorthogonal Wavelet Filter Banks. This filter bank belongs to the half-band-pair filter class and is defined by two kernel functions. Adaptive Bernstein polynomials are used to construct kernel functions. Bernstein polynomial parameter design is achieved by least square method. The first step, decomposition of low-pass filter design. The second step is to design a reconstructed low-pass filter. In a two-stage approach, the design process is effective, including solving linear equations. This design method can easily design different characteristics.
