【摘要】：軟件無線電是一種新興的無線電廣播通信技術(shù),其核心思想是在一個通用的、標(biāo)準(zhǔn)的、模塊化的硬件平臺上用軟件來實現(xiàn)無線電臺的各種功能。具體實現(xiàn)上來講,可通過下載和更新軟件來升級頻帶信息、接口協(xié)議和功能等,通過動態(tài)加載新的波形和協(xié)議,它能夠重新編程或配置,以此來實現(xiàn)不同的應(yīng)用。本文針對上述理論,結(jié)合當(dāng)今的硬件工藝水平和數(shù)字信號處理技術(shù),以可實現(xiàn)為出發(fā)點,設(shè)計了一種可重構(gòu)的數(shù)字信號處理系統(tǒng),該系統(tǒng)采用開放的VPX架構(gòu),將組成該平臺的各種組件或元素以搭積木的方式拼湊組合,通過軟件配置實現(xiàn)不同的應(yīng)用。本平臺的核心是中頻信號處理模塊,在實際應(yīng)用中以中頻信號處理主板搭載FMC子卡的方式提供支撐豐富的外圍接口,同時在模塊的設(shè)計過程中通過對I/O模塊、數(shù)據(jù)處理模塊等進(jìn)行模塊化的處理,以達(dá)到可同時使用于多個項目的目的。本文主要做了以下工作:1、研究了軟件無線電、數(shù)字信號處理的基本理論,對可重構(gòu)技術(shù)、VPX總線技術(shù)等進(jìn)行了重點研究;2、在對可重構(gòu)技術(shù)的深入理解下,設(shè)計出一種基于VPX架構(gòu)的可重構(gòu)高速信號處理平臺的實現(xiàn)方案,對其平臺組成、系統(tǒng)功能以及架構(gòu)設(shè)計等做了詳細(xì)闡述;3、完成中頻信號處理主板的設(shè)計和實現(xiàn),包括主板的設(shè)計思想、基本架構(gòu)、主要器件的選型、主板的原理圖詳細(xì)設(shè)計;4、完成FMC子卡的設(shè)計和實現(xiàn),包括子卡的結(jié)構(gòu)要素設(shè)計、主要器件的選型、FMC子卡的原理圖設(shè)計和PCB設(shè)計;5、搭建可重構(gòu)平臺,對中頻信號處理模塊和該平臺的軟件可重構(gòu)性進(jìn)行了測試和驗證。本文的研究工作主要基于實際項目,已經(jīng)應(yīng)用于各課題中。
[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.
