【Abstract】 Software radio receiver is based on a versatile programmable platform, which can realize different molds . With the development of digital signal processing, it is being possibility to realize the great idea of software radio. This paper discussed high-speed data acquisitions and multi-speed processing which are the key techniques of the software radio .Then, on the basis of these, the paper adopts IF digitalization project based on multi-speed processing model according the present chip level. Finally, taking the AM signal as an example, simulation has verified the feasibility and implementation of the proposal.更多还原
