A Design and Implementation of Decimation Filter Chain Used in Digital Down Converter (DDC)

Xue Ji-hu

Abstract

Data decimating is one of the core technology in digital down converter(DDC);the performance of receiver can be influenced by the design quality of decimation filter chain.In this paper,decimation filter chain with total decimation factor 256 is presented at first,and then Matlab software is used to simulate the performance of it.Finally,the Scheme is carried out by digital down converter HSP50216.
