摘　　要：对基于窗函数设计的FIR滤波器的特性进行了分析,并分别采用矩形窗、Hanning窗和Hamming窗设计FIR滤波器来仿真带限通信信道.Matlab仿真结果表明:基于Hamming窗函数设计的FIR滤波器仿真带限通信信道,效果较好.In this paper,the characteristics of FIR filter based on the design of window function are analysed and the band-limited communication channel is simulated with FIR filter which is designed respectively based on rectangle windows,Hanning window and Hamming window.Simulation with Matlab indicates that the FIR filter based on Hamming window is more effective.

关 键 词：窗函数 FIR滤波器 带限信道
