摘要
介绍积分梳状滤波器(CASCADEDINTEGRATOR-COMB,CIC)和半带滤波器(HALF-BAND,HB)在一种基于软件无线电技术的中频数字接收机中的设计与应用,包括数学原理、性能分析及设置等。通过分析和仿真证明,5级CIC和5级HB级联可以达到比较理想的效果。
CIC filter and half-band filter are two kinds of important digital filters. Its design and configuration is crucial to the receive of system. In this paper, the application and design of the two kinds of filters in IF digital receiver based on the technology of software radio are discussed, including the mathematical principle, function analysis and settings. The results of the analysis and simulation indicate that using 5 stages CIC and 5 stages HB can achieve good effect.
