【摘要】：随着通信系统的不断发展,软件无线电技术扮演着越来越重要的角色。基于CPCI的软件无线电技术在可靠性和扩展性方面更是有着不可替代的地位。现如今,已经有许多团队和厂商开发出了符合CPCI标准的软件无线电平台系统,技术已经相对成熟。传统的软件无线电平台大多基于单片FPGA或DSP来实现。然而,随着数据采集量的不断提高,软件无线电平台的信号处理能力也需要进一步提升,传统的软件无线电平台已经不能完全满足现代信号处理能力的要求。因此,论文设计了新型的软件无线电平台,采用5片FPGA作为核心器件组成FPGA阵列,同样基于CPCI架构,能够进行高速数据交互,提供强大的信号处理能力。根据新型软件无线电平台的方案设计,最终开发出一套完整的硬件平台。首先,描述软件无线电技术的现状和基本结构,结合CPCI标准,总结CPCI架构的优点和局限性,同时列举和对比了现在一些前沿厂商的代表性产品。然后,提出了新型软件无线电技术的功能需求和技术指标,根据技术指标,大体确定平台的架构和功能,进行FPGA阵列软件无线电硬件平台总体方案的设计。接着,在总体设计方案基础上,结合无线电平台的性能指标,进行芯片选型,然后分模块独立设计,分模块完成后,进行模块间设计,进而完成整个系统平台设计。同时也考虑了软件无线电散热性以及可靠性等方面的设计。最后,进行调试和测试,主要是验证电路功能,包括了平台冷板测试,电源和时钟调试,各个模块测试等。论文设计实现的FPGA阵列软件无线电硬件平台,具有数字信号处理能力强,硬件平台可靠性高等特点,可满足科研高校和院所的不同需求。FPGA阵列软件无线电平台具备良好的产品化应用前景。
[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.
