| This paper present, the design and simulation of multi rate decimation filter to work with wireless mobile system under software defined radio (SDR) technology. The decimation filter is designed with three stages of decimation filter that consists of Cascaded Integrated Comb (CIC) decimation filter, Compensating Finite Impulse Response (CFIR) filter and Programmable Finite Impulse Response (PFIR) filter. The three cascaded filters could operate to reduce the intermediate frequency from 100MHz to 100 KHz baseband signal in order to more processing. System Generator offers the multiplier less Multiply-Accumulate (MAC) Finite Impulse Response block which reduce the implementation area. The three filters are designed and simulated using MATLAB and verified with System Generator design from Xilinx. Results obtained from the simulations and verification of this design, has shown that the proposed algorithm reduces the error to 2x10-4 between MATLAB design and System generator. The techniques used are promising, and also develops the sample rate conversion of current wireless systems and new generation of wireless communication system up to 100MHz in IF band. | ||
