[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.
