Software Radio breaks through the restriction of the traditional single functionand weakly expansibility. The basic idea is satisfy the different demand by configuredifferent software on the same hardware. So it possesses very good currency andagility. Now it is a focus of military communication and personal mobilecommunication and micro-electronics fields.Digital down converting is one of the key technologies of software radio. It canimprove the efficiency and reliability of communications. It is also important torealize software radio receivers. The paper focuses on the technologies involved insampling theory, digital orthogonal demodulation, integral sampling rate convert,fractional sampling rate convert ,carrier frequency tracking and symbal tracking.Based on these theory, the paper gives the practically structure, puts forward theapplications based on the HSP50214B Programmable Downconverter and HSP50210Digital Costas Loop. After complete the design of the software and the hardwarerealization, introduce the analysis of the testing results. The performance is identicalto the design request.
