【摘要】：隨著信息化戰(zhàn)爭的發(fā)展,一體化聯(lián)合作戰(zhàn)已經(jīng)成為現(xiàn)代戰(zhàn)爭的發(fā)展趨勢,為了解決部隊各軍兵種進行聯(lián)合作戰(zhàn)時所遇到的“互聯(lián)互通互操作”問題,提出和發(fā)展了SDR(Software Defined Radio)技術。另一方面,手持終端已經(jīng)成為未來信息化戰(zhàn)場上不可或缺的一部分,然而低功耗、小型化、安全可靠等設計要求是手持終端發(fā)展亟需解決的問題。針對上述需求,本文引入了國產(chǎn)多核多線程DSP(Digital Signal Processor)芯片SB3500對基于軟件無線電的手持終端展開研究。首先,本文對當前SDR領域所使用的并行基帶處理架構展開了研究,針對SDR手持終端的低功耗、小型化、安全可靠等設計約束,對架構設計提出了進一步要求。在此二者基礎上,提出了使用國產(chǎn)多核多線程芯片SB3500進行SDR手持終端開發(fā)的方案,并對該芯片展開了進一步的分析。其次,分析了SDR中流水式、總線式、交換式以及計算機和網(wǎng)絡式這四種典型硬件體系架構的架構特點。針對手持終端的低功耗、小型化要求,利用流水式架構結構簡單、信息交互效率高的特點,設計了一款基于SB3500的流水式硬件系統(tǒng)架構。最后,本文設計了一套基于SB3500硬件系統(tǒng)的OFDM(Orthogonal Frequency Division Multiplexing)通信波形軟件,作為該系統(tǒng)的并行化示例波形。針對其中的物理層基帶處理并行調度算法與核間通信接口展開了具體設計。通過搭建測試平臺對所設計的通信系統(tǒng)進行了測試與驗證。驗證了采用SB3500進行SDR手持終端波形并行設計的可行性,并對未來工作進行了展望。
[Abstract]:With the development of information war, the integrated joint operation has become the development trend of modern war. In order to solve the problem of "interconnection and interoperability" encountered in the joint operations of all arms and services of the army. On the other hand, handheld terminal has become an indispensable part of the future information battlefield. However, the design requirements of low power consumption, miniaturization, security and reliability are the problems that need to be solved in the development of handheld terminals. In this paper, the domestic multi-core and multi-thread DSP(Digital Signal processor (SB3500) chip is introduced to study the handheld terminals based on software radio. In this paper, the parallel baseband processing architecture used in the field of SDR is studied, aiming at the design constraints such as low power consumption, miniaturization, security and reliability of SDR handheld terminals. On the basis of these two requirements, a scheme of developing SDR handheld terminal using domestic multi-core multi-thread chip SB3500 is put forward. The chip is further analyzed. Secondly, the income type and bus type in SDR are analyzed. In view of the low power consumption and miniaturization of the handheld terminal, the paper makes use of the simple structure of income architecture and the high efficiency of information exchange. Design a income hardware system architecture based on SB3500. Finally. A set of OFDM(Orthogonal Frequency Division Multiplexing based on SB3500 hardware system is designed in this paper. Communication waveform software. As an example wave of parallelism in this system, the parallel scheduling algorithm of physical layer baseband processing and the communication interface between cores are designed. The designed communication system is tested and tested by building a test platform. The feasibility of parallel design of SDR handheld terminal waveform using SB3500 is verified. The future work is prospected.
