摘要

提出了一种简单的基于锐化技术的无乘法器CIC补偿滤波器。该滤波器既能提供窄带补偿,又能在抽取后占总频带34分之一的频带内进行宽带补偿。设计参数为整数b,它取决于级联CIC滤波器的数量。b的值在MATLAB中通过不同的仿真得到的表格中给出。

Design of CIC Compensator Filter in a Digital IF Receiver
This paper presents a simple multiplier less CIC compensation filter based on the sharpening technique. The proposed filter provides the narrowband compensation, as well as the wideband compensation in the band which is frac34 of the overall band after decimation. The design parameter is the integer b which depends on the number of the cascaded CIC filters. The values of b are given in the table obtained using different simulations in MATLAB.
