In some secure communication system, to detect the frequently varied baseband signal, a digital down converter (DDC) with a variable digital filter is used. In this paper, a reconfiguration design process of DDC is discussed for a GSM application with the help of Xilinx system generator (XSG) on field programmable gate array (FPGA). The approach is based on hardware Co-simulation based on XSG platform which integrates itself with the Matlab based Simulink graphics environment and implemented on Virtex-II based xc2v200-4fg676 FPGA device. Optimal equiripple technique implements DDC which reduces the resource requirement. To solve the complexity, a novel type of polyphase decomposition structure is used. Keeping the view of the system performance, such as area and speed, this paper proposes a model which is implemented by using embedded multiplier, LUTs and BRAM of FPGA. It is seen that the proposed design consumes very less resources available on target devices.
