低复杂度HBCEM FRM多相滤波器组
Low Complexity HBCEM FRM Polyphase Filter Bank
摘要
Abstract
Aimed at the problem of high computation complexity by the narrower of sub-channel transition, the essential reason of HBCEM FRM filter for high efficiency is analyzed.Then, combining with the thought of multi-phase filtering, two HBCEM FRM uniformity filter banks are proposed by using HBCEM FRM filter as a prototype filter.The filter banks have lower computation complexity than conventional FRM filter bank when the transition bandwidth of the prototype filter is sharp.Finally, the complexity analysis and the design example are used to illustrate the feasibility.关键词
