[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.
