Abstract : Based on software radio architecture, the principle of convergence node IF receiver hardware and software design is
proposed. This paper analyzes the digital model of convergence node IF receivers, and the different designs pared to
determine the design according to design requirements. Using electronic design automation technology and FPGA to design digital
down conversion plete the receiver function. It simulates the system by MA
