Cascaded Integrator Comb (CIC) filters are widely used in multi-rate digital signal processing for both the decimation and interpolation. Digital down converter is plays important role in wireless communication system. In this paper, the authors can design FPGA based optimized decimation filters for wireless communication receivers. Digital Down Converter (DDC) utilizes the major resources and cost efficient. In DDC, they can design DDS to generate the arbitrary wave forms. However, the proposed filters is designed to decimate the signal high sample rate to low sample rate.
