【摘要】:自20世紀80年代至今,移動通信技術經過了飛速發(fā)展的階段,已經從最初的第一代移動通信技術發(fā)展到了第四代移動通信技術(4G)。移動通信設備越來越普及,逐漸成為了日常生活中必不可少的一部分,使消費者享受到了更加快速、便捷的業(yè)務。移動通信技術的快速發(fā)展和應用領域的不斷擴展,這就迫使了接收機的功能性和使用性能不斷提高。隨著軟件無線電理論的提出,基于軟件無線電原理設計的接收機已經得到了普遍應用,特別是在移動通信基站、數(shù)字廣播電視、雷達等方面,其應用場景更加廣泛。以FPGA為代表的信號處理芯片由于其高效的處理能力逐漸成為數(shù)字接收機的不可缺少的組成部分。結合高性能的FPGA芯片的使用,在以軟件無線電的方式對信號進行處理時能夠更加高效和穩(wěn)定。本文針對移動通信基站信號接收機進行研究,最終目的是能夠通過對基站信號的處理從而對基站進行監(jiān)測。介紹了移動通信基站監(jiān)測的理論方法,提出了接收機的兩種實現(xiàn)方案:方案一:傳統(tǒng)的基于FPGA+PC的接收機方案,通過FPGA硬件平臺完成基站信號的能量檢測、數(shù)據(jù)采集等預處理工作,然后在PC端對預處理后的信號進一步分析,完成基站的監(jiān)測。方案二:為了適應移動通信技術的快速發(fā)展,未來能夠對高速率、高帶寬的信號進行處理,提出了具有通用性和可擴展性的基于PCI Express總線信號處理平臺的接收機方案。該方案以可擴展的PCI Express總線信號處理平臺為基礎,可通過擴展接口根據(jù)要實現(xiàn)的功能選擇相應的信號處理板卡,各個板卡之間的數(shù)據(jù)可以通過PCI Express總線進行高速傳輸,該方案集成度高、靈活性強、通用性強。完成了方案一的設計,并且進行了整體的測試,測試結果表明了方案的正確性。方案二完成了基于PCI Express總線的通用信號處理平臺的設計。
[Abstract]:Since the 1980s, the mobile communication technology has passed through the rapid development stage, has developed from the first generation of mobile communication technology to the fourth generation of mobile communication technology. Mobile communication devices are becoming more and more popular and become an indispensable part of daily life, which makes consumers enjoy faster and more convenient business. With the rapid development of mobile communication technology and the continuous expansion of application field, the receiver's function and performance are improved continuously. With the development of software radio theory, the receiver based on software radio theory has been widely used, especially in mobile communication base station, digital broadcast television, radar and so on. Signal processing chip represented by FPGA has become an indispensable part of digital receiver because of its high efficiency. Combined with the use of high performance FPGA chips, it can be more efficient and stable in the processing of signals in the way of software radio. In this paper, the signal receiver of mobile communication base station is studied, and the final purpose is to monitor the base station by processing the base station signal. This paper introduces the theory and method of mobile communication base station monitoring, and puts forward two realization schemes of receiver: one is the traditional receiver scheme based on FPGA PC, and the other is the energy detection of base station signal through FPGA hardware platform. Data acquisition and other preprocessing work, and then on the PC side of the pre-processed signal further analysis, the completion of the base station monitoring. Scheme two: in order to adapt to the rapid development of mobile communication technology and to process high speed and high bandwidth signals in the future, a receiver scheme based on PCI Express bus signal processing platform is proposed. The scheme is based on the scalable PCI Express bus signal processing platform, and the corresponding signal processing board can be selected according to the function to be realized through the extended interface. The data between the boards can be transmitted at high speed through the PCI Express bus. The scheme is highly integrated, flexible and versatile. The design of scheme one is completed, and the whole test is carried out. The test results show that the scheme is correct. The second scheme completes the design of the general signal processing platform based on PCI Express bus.
