【摘要】：软件无线电具有灵活、开放、可重构的特点,可以缩短开发周期,降低系统升级换代的成本。软件无线电平台主要功能之一是高速数据传输,如何实现高速数据传输是软件无线电平台设计的一个关键问题。目前,软件无线电平台与PC进行高速数据传输常用外设接口包括USB、PCIE、1394等。但是,利用这些接口实现高速数据传输时,传输距离比较短,不能实现网络传输,不利于远程控制;硬件接口实现难度比较大,应用程序开发相对复杂。为此,论文在软件无线电平台上,通过以太网实现了软件无线电平台与PC通信,提高了传输距离,降低了程序开发难度,增强了数据接口可移植性。论文主要完成了以下几个方面工作:第一,实现了以太网协议栈,设计了软件无线电平台与PC之间通信对等传输数据通道。协议栈包括ARP、IP、UDP、PING等协议,利用协议栈实现PC与软件无线电平台UDP通信;通过数据通道,实现了高速数据传输、参数配置、状态监测和流量控制。第二,完成了软件无线电平台间的数据透明传输。论文中给出了物理层和MAC层两种数据透明传输方案,但是物理层数据透明传输丢包率比较高。在对物理层透明传输方案进行改进之后,实现了软件无线电平台间MAC层数据透明传输。第三,验证了以太网高速数据通道的功能和性能。验证结果表明,PC与软件无线电平台实现了对等传输通信,双通道回环验证时,数据传输速率最高可以达到951Mbps;利用软件无线电平台之间的数据透明传输,实现了PC间通信,PC间TCP数据传输速率最高可以达到758Mbps,UDP数据传输速率最高可以达到928Mbps,丢包率为0.24%。论文实现了软件无线电平台与PC间以太网高速数据通信;利用软件无线电平台透明传输,实现了PC间通信,数据传输速率满足了高速数据通信的需求。论文成果已经运用到实际产品中,具有一定的实用价值。
[Abstract]:Software radio is flexible, open and reconfigurable, which can shorten the development cycle and reduce the cost of system upgrading. High speed data transmission is one of the main functions of software radio platform. How to realize high speed data transmission is a key problem in the design of software radio platform. At present, the software radio platform and PC high-speed data transmission commonly used peripheral interfaces, including USB,PCIE,1394 and so on. However, when these interfaces are used to realize high-speed data transmission, the transmission distance is relatively short and the network transmission can not be realized, which is not conducive to remote control, and the implementation of hardware interface is difficult and the development of application program is relatively complex. Therefore, on the software radio platform, the communication between the software radio platform and PC is realized through Ethernet, the transmission distance is improved, the difficulty of program development is reduced, and the portability of data interface is enhanced. The main work of this paper is as follows: first, the Ethernet protocol stack is implemented, and a peer-to-peer data transmission channel between the software radio platform and PC is designed. The protocol stack includes ARP,IP,UDP,PING and other protocols. The protocol stack is used to realize the communication between PC and the software radio platform (UDP), and the high-speed data transmission, parameter configuration, state monitoring and flow control are realized through the data channel. Secondly, the transparent data transmission between the software radio platform is completed. In this paper, two kinds of data transparent transmission schemes, physical layer and MAC layer, are presented, but the packet loss rate of physical layer data transparent transmission is relatively high. After improving the physical layer transparent transmission scheme, the MAC layer data transparent transmission between the software radio platform is realized. Thirdly, the function and performance of Ethernet high-speed data channel are verified. The verification results show that the PC and the software radio platform realize the peer-to-peer transmission communication, and the maximum data transmission rate can reach 951 Mbps. the data transmission between the software radio platform and the software radio platform is transparent, and the data transmission rate can be up to 951 Mbps. The TCP data transmission rate between PC can reach 758 MbpsU UDP data transmission rate up to 928 Mbpss, and the packet loss rate is 0.24 Mbps. In this paper, the Ethernet high-speed data communication between software radio platform and PC is realized, and the communication between PC is realized by transparent transmission of software radio platform, and the data transmission rate meets the demand of high-speed data communication. The results of this paper have been applied to practical products and have certain practical value.
