dc.description.abstractThe main aim of this research is the design and implementation of the Digital Down Converter (DDC) filter with low passband ripple and high attenuation in the adjacent rejection and blocker requirements in the filter response for Software Defined Radio (SDR) transceiver to decrease the power consumption and avoid the interference in the channel. The proposed DDC filters incorporate of Remez algorithm and Mini-max algorithm to reduce the error rate in the filter response. The DDC filter is a combination of 5-stages Cascaded Integrated Comb (CIC) filter and two linear phase Equiripple FIR filter (CFIR and PFIR). The passband ripple, adjacent rejection and blocker band is developed by controlling the transition width, filter order and weight function of the FIR filter using MATLAB and Xilinx System Generator environment. Additionally, the transmitter and receiver baseband section of SDR transceiver has been designed and implemented under channel noise to verify the filter performance in the SDR receiver. The input and output signals are analyzed and evaluated on a real time basis by translating all signals in Verilog code and verified using ModelSim for the FPGA implementation. The simulation and implementation results of DDC filter show that the proposed algorithms provide an important developments of 40% in the passband ripple, 18% in the adjacent rejection, 11% in the blocker requirements and consume less FPGA logic elements by almost 20 % in term of slices and LUTs as compared with current design. These results confirm the validity of the proposed algorithms and the techniques used are promising to support the SDR requirements of wireless communication system.en_US
