GSM 移动通信系统中低通滤波器的设计与仿真
摘要:本文应用 MATLAB 软件中的 Simulink 平台分别研究了 FIR 数字低通滤波器和
IIR 数字低通滤波器的设计方法和实现方法,并进行模拟仿真设计,以显示本文所介
绍数字低通滤波器的多种特性。
在无限脉冲响应(IIR)数字低通滤波器设计中,应用了冲击响应不变法和双线
性 Z 变换法,先进行模拟滤波器的设计,然后把模拟滤波器转换为数字滤波器,最后
进行滤波器的频带转换,使用 MATLAB 软件按两种方法编辑程序并通过图形展示 IIF
低通滤波器的各种参数和性能指标。在有限脉冲响应(FIR)低通数字滤波器设计中,
讨论了 FIR 线性相位滤波器的特点和用窗函数法设计 FIR 滤波器两个问题。这两类低
通滤波器整个设计过程都是按照理论分析、编程设计、模拟仿真、具体实现的步骤进
行的。

GSM munication system design and simulation of the
low-pass filter
Abstract : In this paper, the application of MATLAB software Simulink platform
respectively studied the FIR digital low-pass filter and IIR low-pass filter design methods
and implementation method, and carries on the simulation design,to display a variety of
characteristics of digital low-pass filter, presented in this paper.
In infinite impulse response (IIR) digital low-pass filter design, the application of
shock response is not political reform and bilinear z-transform method, first for the design
of analog filter, then converted to a digital filter, the analog filter to filter the frequency
conversion, using MATLAB software according to the two methods of editing program
and through the graphic display of IIF low-pass filter parameters and performance
indicators. In finite impulse response (FIR) low-pass digital filter design, discussed the
characteristics of the FIR linear phase filter and FIR filter with window function method
with two problems. These two types of low-pass filter the whole design process is in
accordance with the theoretical analysis, programming design, simulation and
implementation steps.
Keywords: digital low-pass filter, the MATLAB, Simulink,
