Design and Implementation of Digital Up Converter for Homenet

Based on the classical system design flow, a custom digital up converter (DUC) IP is designed and implemented for Homenet system. At the system level, DUC behavior model is constructed and DUC system architecture, spectra distribution scheme and circuit parameters are confirmed with system modeling tool MATLAB. At the circuit level, the main function modules such as interpolator and numerically controlled oscillators (NCO) and so on are designed and implemented. Considering the limited hardware resources and performance specification, a large number of optimizing technologies and algorithm are adopted. At last, Homenet system verification flat including our custom digital up converter system is realized with Xilinx Virtexll XC2V1000-4FG256 FPGA.
