【摘要】：現(xiàn)代電子通信技術(shù)的快速演進,推動著與其休戚相關的誤碼測試技術(shù)地不斷更新發(fā)展。誤碼測試技術(shù)作為通信產(chǎn)品的重要設計測試驗證手段,其測試中間結(jié)果和最終結(jié)果能有效的輔助技術(shù)人員對在研、在產(chǎn)的通信設備的工作可靠性、穩(wěn)定性做出判別�，F(xiàn)今通信產(chǎn)品早已將誤碼率等誤碼測試數(shù)據(jù)作為其自身重要的技術(shù)指標,納入產(chǎn)品的設計之中。而誤碼測試技術(shù)作為一項重要的通信指標,在應用面上也并不僅僅限制使用語通信產(chǎn)品的設計驗證階段,其還能靈活的應用于通信產(chǎn)品后期的生產(chǎn)驗收、安裝調(diào)試和運營維護等階段,這幾乎涵蓋了通信產(chǎn)品的整個生命周期。目前市場在產(chǎn)在售的通用型誤碼測試儀,具備豐富的通信測試接口,精巧的結(jié)構(gòu)設計,多樣化的應用功能,而廣泛使用于不同的通信測試領域。但其精巧的設計和多樣化的功能,需要使用者付出高昂的價格成本,同時其雖然擁有豐富的通信測試接口,但無論如何也無法涵蓋所有的通信接口類型。例如針對GMSK無線數(shù)字調(diào)制信道的誤碼率測試需求,通用的誤碼測試儀在接口上就難以滿足測試應用。為此,技術(shù)人員必須在通用型誤碼測試儀之外單獨設計制作一款GMSK無線數(shù)字調(diào)制信道接口適配器以實現(xiàn)與通用誤碼測試儀的配接,這對測試人員而言通用誤碼測試儀在應用方式上將受限。本論文正是針對上述問題,以GMSK數(shù)字調(diào)制信道的通信產(chǎn)品誤碼測試技術(shù)為主要研究對象,在深入分析GMSK數(shù)字調(diào)制解調(diào)技術(shù),以及當前主流的計算機通信技術(shù)的基礎之上,提出了研制一款基于PCI計算機通信總線接口的GMSK調(diào)制信道誤差測試儀。從經(jīng)濟適用性考慮,為簡化用戶測試環(huán)境搭建,降低開發(fā)成本,本課題大規(guī)模選用了市場上主流的電子信息技術(shù),并借鑒成熟的開發(fā)手段和方法,在硬件設計上采用DSP數(shù)字信字處理器和CPLD復雜可編程邏輯器件作為嵌入式系統(tǒng)核心控制模塊,設計實現(xiàn)了雙通道GMSK調(diào)制解調(diào)信道接口、PCI計算機計算機通信總線接口、誤碼計數(shù)、數(shù)據(jù)位同步和小m序列偽隨機測試碼生成等功能;而在計算機應用軟件設計上采用C++Builder 5.0集成軟件開發(fā)環(huán)境,設計實現(xiàn)了誤碼測試流程控制、誤碼統(tǒng)計、誤碼率計算和人機交互。
[Abstract]:The rapid evolution of modern electronic communication technology promotes the development of error test technology which is closely related to it. As an important means of design and verification of communication products, error test technology can effectively assist technicians to judge the reliability and stability of communication equipment in production and research. Nowadays, the error test data such as bit error rate (BER) has been taken as an important technical index in the design of communication products. As an important communication index, error code testing (BER) is not only limited in the design and verification stage of communication products, but also can be applied to the acceptance of communication products in the later stage. Stages such as installation, commissioning and operational maintenance cover almost the entire lifecycle of the communications product. At present, the universal error-code tester, which is on sale in the market, has rich communication test interface, exquisite structure design and diversified application function, and is widely used in different communication test fields. But its exquisite design and diversified functions require users to pay a high price cost, and although it has a wealth of communication test interfaces, it can not cover all types of communication interfaces in any way. For example, in order to meet the requirements of GMSK wireless digital modulation channel BER test, the universal BER tester is difficult to meet the test application in the interface. Therefore, the technicians must design and manufacture a GMSK wireless digital modulation channel interface adapter in addition to the universal error code tester to realize the connection with the universal error code tester. This will limit the way in which the universal error-code tester is applied to testers. Aiming at the above problems, this paper takes the error code testing technology of GMSK digital modulation channel as the main research object, based on the in-depth analysis of GMSK digital modulation and demodulation technology, as well as the current mainstream computer communication technology. A GMSK modulation channel error tester based on PCI computer communication bus interface is developed. Considering the economic applicability, in order to simplify the construction of user test environment and reduce the cost of development, this paper selects the mainstream electronic information technology in the market on a large scale, and draws lessons from the mature development means and methods. In hardware design, DSP digital word processor and CPLD complex programmable logic device are used as the core control module of embedded system. The dual-channel GMSK modulation and demodulation channel interface and PCI-based communication bus interface are designed and implemented. The functions of data bit synchronization and pseudorandom test code generation of small m sequence, and the design of computer application software using C Builder 5.0 integrated software development environment, designed and realized the error test flow control, error code statistics, Error rate calculation and man-machine interaction.
