[Abstract]:Software radio is a new radio broadcasting communication technology, its core idea is to use software to implement various functions of radio station on a universal, standard, modular hardware platform. The new waveform and protocol can be reprogrammed or configured to achieve different applications. In this paper, a reconfigurable digital signal processing system is designed based on the hardware technology level and digital signal processing technology. This system uses an open VPX architecture to form the platform. The core of this platform is the medium frequency signal processing module. In the practical application, the medium frequency signal is used to carry the FMC subcard to provide the rich peripheral interface, and the I/O module is passed in the module design process. The modules of data processing module are processed to achieve the purpose of using multiple projects at the same time. The following work is done in this paper: 1, the basic theory of software radio, digital signal processing, reconfigurable technology and VPX bus technology are studied. 2, under the deep understanding of reconfigurable technology, the design is designed. An implementation scheme of the reconfigurable high-speed signal processing platform based on VPX architecture is described in detail. 3, the design and implementation of the intermediate frequency signal processing main board are completed, including the design idea of the main board, the basic architecture, the selection of the main components, the detailed design of the main board's schematic diagram, and the complete FM. The design and implementation of the C sub card include the design of the structural elements of the sub card, the selection of the main components, the schematic design of the FMC sub card and the design of the PCB. 5, the reconfigurable platform is built to test and verify the software reconfiguration of the medium frequency signal processing module and the platform. The research work of this paper is mainly based on the actual projects and has been applied in various classes. In the question.
