一种高速半带插值滤波器的设计方法
Design Method for a High-Speed Half-Band Interpolation Filter
摘要
Abstract
In order to fulfill the requirements for data interpolation in high-speed communication systems and digital signal processing,a design methodology for high-speed interpolation filters based on half-band filters is proposed.This approach leverages the coefficient sparsity and symmetry of half-band filters and employs a multi-way parallel architecture to substantially reduce the number of multiplication operations and computational complexity.The frequency-domain characteristics of half-band filters and their applications in interpolation are described in detail.The design procedures,hardware implementation,and resource optimization techniques for the filter are examined.Simulation results demonstrate that this filter design methodology can significantly enhance interpolation speed while maintaining filtering performance,making it well-suited for high-speed and real-time signal processing applications.关键词
