【摘要】：隨著通信技術(shù)的迅猛發(fā)展,基于軟件無線電技術(shù)應(yīng)用研究逐漸成為國內(nèi)外科研單位與高校的研究熱點(diǎn)。在電子通信領(lǐng)域,信號發(fā)生器是一種最常用的儀器設(shè)備,但其中普通信號發(fā)生器僅有信號生成功能,而功能齊全的矢量信號發(fā)生器價格昂貴、體積大。因此借助軟件無線電技術(shù),生成具備某種外界環(huán)境參數(shù)的信號,對構(gòu)建實(shí)際測試場景意義重大。本文旨在研究泛在無線信號產(chǎn)生平臺,分析泛在信號通用設(shè)計(jì)方案,接著優(yōu)化以下幾個方面達(dá)到設(shè)計(jì)目的。第一,本文實(shí)現(xiàn)方式由獨(dú)立硬件電路轉(zhuǎn)變?yōu)檐浻布Y(jié)合。即在個人計(jì)算機(jī)(Personal Computer,PC)上建立通用調(diào)制模型,產(chǎn)生基帶調(diào)制信號,利用外設(shè)部件高速互連(Peripheral Component Interconnect Express,PCI Express)通信鏈路接口,傳輸數(shù)據(jù)至可編程邏輯門陣列(Field Programmable Gate Array,FPGA),進(jìn)行后續(xù)數(shù)字處理。第二,本文對通用模型進(jìn)行改進(jìn),以軟件化的形式增加了噪聲背景、多普勒頻移效應(yīng)和多徑效應(yīng)三種功能,從而使該平臺能夠模擬出實(shí)際工程中特殊應(yīng)用場景。其中在噪聲模型中摒棄傳統(tǒng)噪聲源配件,直接由軟件模擬生成噪聲數(shù)據(jù)。針對多普勒頻移模型,本文改進(jìn)了傳統(tǒng)勻加速模型,根據(jù)速度或加速度函數(shù),建立一種任意速度多普勒頻移模型。對于多徑效應(yīng)模型,在單載波信號模型基礎(chǔ)上,提出一種多載波模型,滿足復(fù)雜環(huán)境參數(shù)需求。總的來說,本文改進(jìn)的三個功能模型比傳統(tǒng)設(shè)計(jì)具有更多優(yōu)勢,能夠應(yīng)用于特殊場合。在設(shè)計(jì)過程中,主要使用MATLAB軟件和ModelSim軟件對上位機(jī)調(diào)制模型、底層信號處理模塊以及PCI Express接口進(jìn)行了相應(yīng)仿真測試。同時還使用矢量信號分析儀對調(diào)制數(shù)據(jù)進(jìn)行驗(yàn)證測試。測試結(jié)果表明,本文所設(shè)計(jì)的基本模塊工作正常。但由于涉及領(lǐng)域廣、工作量較大,仍然存在較多改善之處,將在隨后的工作中繼續(xù)開展。
[Abstract]:With the rapid development of communication technology, the research on the application of software radio technology has gradually become the research hotspot of scientific research institutions and universities at home and abroad. In the field of electronic communication, the signal generator is one of the most commonly used instruments, but the ordinary signal generator has only the function of signal generation, and the full-featured vector signal generator is expensive in price and large in volume. Therefore, it is of great significance to create a signal with some external environmental parameters by means of software radio technology. The purpose of this paper is to study the ubiquitous wireless signal generation platform, analyze the universal design scheme of the ubiquitous signal, and then optimize the following aspects to achieve the purpose of the design. First, the realization mode of this paper is changed from independent hardware circuit to hardware and software combination. That is to build a general modulation model on personal computer (Personal Computer,PC), generate baseband modulation signal, use peripheral components to high speed interconnect (Peripheral Component Interconnect Express,PCI Express) communication link interface, and transmit data to programmable logic gate array (Field Programmable Gate Array,). FPGA), carries on the subsequent digital processing. Secondly, this paper improves the general model by adding three functions of noise background, Doppler frequency shift effect and multipath effect in the form of software, so that the platform can simulate the special application scene in practical engineering. In the noise model, the traditional noise source parts are abandoned and the noise data is generated directly by software simulation. For the Doppler frequency shift model, this paper improves the traditional uniform acceleration model and establishes an arbitrary velocity Doppler frequency shift model according to the velocity or acceleration function. For the multipath effect model, based on the single carrier signal model, a multi-carrier model is proposed to meet the needs of complex environmental parameters. In general, the improved three functional models have more advantages than the traditional design, and can be used in special situations. In the design process, the modulation model, the underlying signal processing module and the PCI Express interface of the host computer are simulated and tested by MATLAB and ModelSim software. At the same time, the vector signal analyzer is used to verify the modulation data. The test results show that the basic modules designed in this paper work well. However, due to the wide range of areas, heavy workload, there are still more improvements, will continue in the subsequent work.
