摘要：In this paper cost effective reconfigurable WCDMA DUC design has been presented for mobile communication base stations. The WCDMA DUC has been designed and implemented by combining the multiplier less and multiplier based techniques to achieve an optimized hybridized solution for mobile applications. The different sections of DUC have been optimized separately and then combined together. The Park McClellan algorithm has been used for optimal filter length to reduce hardware requirements along with computationally efficient polyphase decomposition technique to optimize both speed and area. The embedded multipliers and LUTs of target FPGA are efficiently utilized to enhance the system performance. The proposed DUC has been designed with Matlab, synthesized with Xilinx Synthesis Tool (XST) and implemented on Virtex-II Pro based xc2vp30-7ff896 FPGA device. The developed DUC can operate at a maximum frequency of 147 MHz by efficiently utilizing the resources available on target FPGA to provide cost effective solution for SDR based wireless applications.
