Design of CIC Compensator Filter in a Digital IF Receiver

Abstract

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.
