[Abstract]:With the development of communication system, software radio technology plays a more and more important role. Software radio technology based on CPCI plays an irreplaceable role in reliability and expansibility. Nowadays, many teams and vendors have developed software radio platform systems that meet the CPCI standard, and the technology is relatively mature. Most of the traditional software radio platforms are based on monolithic FPGA or DSP. However, with the continuous improvement of data acquisition, the signal processing capability of the software radio platform needs to be further improved. The traditional software radio platform can not fully meet the requirements of the modern signal processing capability. Therefore, a new software radio platform is designed, which uses five pieces of FPGA as the core device to form the FPGA array. It is also based on the CPCI architecture, which can carry out high-speed data interaction and provide powerful signal processing capability. According to the scheme design of the new software radio platform, a complete hardware platform is developed. Firstly, this paper describes the current situation and basic structure of software radio technology, summarizes the advantages and limitations of CPCI architecture, and lists and compares the representative products of some leading edge manufacturers. Then, the functional requirements and technical specifications of the new software radio technology are put forward. According to the technical specifications, the framework and function of the platform are generally determined, and the overall scheme of the hardware platform of FPGA array software radio is designed. Then, on the basis of the overall design scheme, combining with the performance index of the radio platform, chip selection is carried out, and then the modules are designed independently. After the modules are completed, the inter-module design is carried out, and the whole system platform design is completed. At the same time, the design of software radio heat dissipation and reliability is also considered. Finally, debug and test, mainly verify the function of the circuit, including platform cold board test, power supply and clock debugging, each module test and so on. The FPGA array software radio hardware platform designed and implemented in this paper has the characteristics of strong digital signal processing ability, high reliability of hardware platform, and so on. It can meet the different needs of scientific research universities and institutes. FPGA array software radio platform has a good prospect of production and application.
