过采样近似完全重构 DFT 调制滤波器组的设计。首先,分析了传递函数和 混叠传递函数的性质，给出了因果 FIR DFT 调制滤波器组的系统延迟与线性相位 分析和综合原型滤波器阶数的关系。随后，过采样近似完全重构 DFT 调制滤波器 组的设计问题被描述为一个非凸优化问题。-Near perfect reconstruction oversampled DFT modulated filter design. First, the analysis of the transfer fun

分析并综合了联邦滤波算法，以及该算法存在的问题，提出了针对观测信息不足的情况下的算法-Analysis and synthesis of the federated filtering algorithm, as well as the problems of the algorithm is proposed for the observed absence of sufficient information the algorithm

This routine returns the coefficients of the 𝑁 -coefficient symmetric prototype filter 𝐻 (𝑧 ). The coefficients are normalized to have energy 1/2. When the analysis and synthesis filters are configured as shown above, the overall
