【摘要】：自20世纪80年代至今,移动通信技术经过了飞速发展的阶段,已经从最初的第一代移动通信技术发展到了第四代移动通信技术(4G)。移动通信设备越来越普及,逐渐成为了日常生活中必不可少的一部分,使消费者享受到了更加快速、便捷的业务。移动通信技术的快速发展和应用领域的不断扩展,这就迫使了接收机的功能性和使用性能不断提高。随着软件无线电理论的提出,基于软件无线电原理设计的接收机已经得到了普遍应用,特别是在移动通信基站、数字广播电视、雷达等方面,其应用场景更加广泛。以FPGA为代表的信号处理芯片由于其高效的处理能力逐渐成为数字接收机的不可缺少的组成部分。结合高性能的FPGA芯片的使用,在以软件无线电的方式对信号进行处理时能够更加高效和稳定。本文针对移动通信基站信号接收机进行研究,最终目的是能够通过对基站信号的处理从而对基站进行监测。介绍了移动通信基站监测的理论方法,提出了接收机的两种实现方案:方案一:传统的基于FPGA+PC的接收机方案,通过FPGA硬件平台完成基站信号的能量检测、数据采集等预处理工作,然后在PC端对预处理后的信号进一步分析,完成基站的监测。方案二:为了适应移动通信技术的快速发展,未来能够对高速率、高带宽的信号进行处理,提出了具有通用性和可扩展性的基于PCI Express总线信号处理平台的接收机方案。该方案以可扩展的PCI Express总线信号处理平台为基础,可通过扩展接口根据要实现的功能选择相应的信号处理板卡,各个板卡之间的数据可以通过PCI Express总线进行高速传输,该方案集成度高、灵活性强、通用性强。完成了方案一的设计,并且进行了整体的测试,测试结果表明了方案的正确性。方案二完成了基于PCI Express总线的通用信号处理平台的设计。
[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.
