本文提出了一种格型结构的双正交线性相位滤波器组（BOLPFBs）使用新的积木，它可以获得较长的滤波器比传统的积木的数量较少。该结构是从一阶LPFBs的构建块的泛化。此外，所提出的构建块适用于偶数和奇数信道。所得到的光纤带具有良好的阻带衰减性能和较低的实现成本。
This paper proposes a lattice structure of biorthogonal linear-phase filter banks (BOLPFBs) using new building blocks which can obtain long filters with fewer number of building blocks than conventional ones. The structure is derived from a generalization of the building blocks of first-order LPFBs. Furthermore, the proposed building blocks are applicable for both even and odd number of channels. The resulting FBs have good performance in stopband attenuation and low implementation costs.
