| 摘 要： | 信道化作为软件无线电系统和宽带数字接收机的关键技术之一,而多相滤波结构的信道化处理技术和滤波器组的设计一直是研究难点。根据多相滤波结构,本文给出一种有限冲激响应滤波器的设计方法,然后根据均匀信道化的要求设计出均匀滤波器组,设计出的原型滤波器能够无失真采样滤波并能重构。利用等波纹设计的同时,使优化所得通带波纹数量级达到10-3,衰减达到-100dB。利用MATLAB设计及仿真表明,该设计是可靠的,可作为高速率滤波器设计的方法。

| Abstract: | The channelzation by way of software wireless system and wide-band digital receiver one of the key technologies,the design right through difficulty of the thereinto filter bank and Polyphase filter structure of the channelization processing.According to polyphase filter structure, this paper presents a finite impulse response filter design method, suffice of the uniform channel filter bank design.Utilization equation of corrugated design, the optimized passband ripple magnitude from 10-3 and the attenuation reach to -100 dB.Design and use of mat.lab simulation show that the design is reliable, can be used as high-speed filter design methods. |
