摘要

为实现时域重叠信号的全概率接收和跨信道信号重构，降低窄过渡带信道化结构的复杂度，提出一种基于调制屏蔽滤波器频率响应屏蔽（Modulation Masking Filter Frequency Response Masking， MMF-FRM）技术的信道化接收机结构.通过对原型屏蔽滤波器进行调制得到两个分支屏蔽滤波器，给出了基于MMF-FRM的窄过渡带滤波器设计方法.推导出一种基于MMF-FRM的低复杂度信道化接收机结构，该信道化结构解决了多相分解受FRM（Frequency Response Masking）滤波器组限制的问题，并分析了该结构的有限字长性质和纹波系数.用Xilinx System Generator进行了硬件实现与仿真，在采样速率为1 GHz，信道数为8的条件下，提出的信道化接收机结构比多相信道化结构节省74.1%的乘法器资源，比FRM信道化结构节省13.5%的乘法器资源.

Abstract

In order to realize the full probability reception of time-domain overlapping signals and cross-channel signal reconstruction

reduce the complexity of channelized structure with narrow transition bandwidth

a channelized receiver structure based on modulation masking filter frequency response masking (MMF-FRM) is proposed. Two branch masking filters are obtained by modulating the prototype masking filter

and the MMF-FRM based narrow transition bandwidth filter design method is presented. A low complexity channelized receiver structure based on MMF-FRM is derived. This structure solves the problem of polyphase decomposition limited by frequency response masking (FRM) filter bank

and the finite word length property and ripple of this structure are analyzed. The hardware implementation and simulation are carried out using the Xilinx System Generator. Under 1 GHz sampling frequency and 8 channels condition

the proposed channelized receiver structure saves 74.1% multiplier resources compared with the polyphase channelized receiver structure

and 13.5% compared with the FRM channelized structure.
