【摘要】：目前,在民用研究上软件无线电具有广阔的发展空间。在无线通信领域中,许多通信协议大量涌现,导致出现新的协议无法与旧协议相互兼容的问题,以及升级困难等问题。由于软件无线电平台采用软件进行技术革新,该平台具有一定的灵活性以及高度适应性,可以实现在兼容旧的通信协议的同时,又可以通过软件的升级更新成最新的协议。大量研究表明,为了适应目前更加高速发展的通信环境,单采用FPGA实现软件无线电传输系统,会出现许多不足,需要提高处理器的处理速度、通信稳定性、人机交互等其它附加功能。本设计采用了 Xilinx公司最新研发的Zynq-7000系列,将最新工艺的ARM处理器和FPGA可编程逻辑器件集成在一块芯片上,实现了最新一代的全可编程片上系统。利用单片解决方案实现的软件无线电平台真正做到了在性能、成本、功耗等设计预算上的完美折衷。论文主要针对Zynq-7000系列结合ADI公司所研发的AD9361捷变射频收发器设计软件无线电平台。首先分析如何实现该软件无线电系统的硬件及软件结构,主要分析了系统的底层硬件接口、平台处理系统,以及系统启动等问题。最后GUI工具实现人机交互平台,用IEEE802.1 1a基带传输来验证该软件无线电平台的可实现性,最后对IEEE802.1 1a基带传输接收到的结果进行系统分析。
[Abstract]:At present, software radio has a broad development space in civil research. In the field of wireless communication, a large number of communication protocols have emerged, resulting in the new protocols can not be compatible with the old protocols, as well as problems such as the difficulty of upgrading. Because the software radio platform adopts software to carry on the technical innovation, this platform has certain flexibility and high adaptability, can realize the compatibility with the old communication protocol, but also can update to the newest protocol through the software upgrade. A large number of studies have shown that in order to adapt to the more rapid development of the communication environment at present, it is necessary to improve the processing speed and communication stability of the processor by using FPGA alone to implement the software radio transmission system. Other additional functions such as human-computer interaction. This design adopts the latest Zynq-7000 series developed by Xilinx Company, integrates the latest process ARM processor and FPGA programmable logic device on a single chip, and realizes the newest generation of full programmable chip system. The software radio platform realized by monolithic solution achieves the perfect tradeoff in performance, cost, power consumption and other design budget. This paper mainly aims at designing software radio platform of Zynq-7000 series combined with AD9361 agile RF transceiver developed by ADI company. Firstly, the hardware and software structure of the software radio system is analyzed. The hardware interface, platform processing system and system startup are analyzed. Finally, the human-computer interaction platform is implemented by GUI tool, and the realization of the software radio platform is verified by IEEE802.1 1a baseband transmission. Finally, the results of IEEE802.1 1a baseband transmission are analyzed systematically.
