【摘要】：随着无线通信的快速发展,一方面,传统基于专用硬件实现的通信设备由于功能较少、工作模式单一,造成不同通信系统之间无法实现互联,而且升级困难。另一方面,软件无线电技术突破了传统电台的局限性,采用软件编程方式即可实现无线电的各种功能,与传统专用电台相比,具有更高的灵活性。然而,目前的软件无线电平台受硬件结构限制,可扩展性较低;受开发周期的限制,灵活性仍有待提高。针对上述问题,本文研究广义的基于网络的可伸缩软件无线电平台,兼容传统专用硬件设备与软件无线电平台。为解决软件无线电平台可扩展性低、传统专用硬件设备难于升级与互联的问题,论文设计了基于网络的可伸缩软件无线电平台架构。所设计的可伸缩软件无线电平台架构通过网络协议组建局域网,实现对异构传输设备与不同无线网络的集成,并可根据实际需求规划网络中的设备数量与类型,有效改善了软件无线电平台的可扩展性与灵活性。进一步,具体设计了兼容异构传输设备的网络融合方案。传输设备包括基于通用处理器的软件无线电平台、可编程的商用调制/接收卡、数字广播接收机、嵌入式传输平台以及GPRS网络传输平台。通过设计调度控制程序,可兼容异构传输设备与异构无线网络。测试结果表明,本文实现的软件无线电平台架构可快速搭建部署兼容多种无线通信系统的可靠传输网络。综上所述,本文设计实现了基于网络的可伸缩软件无线电平台架构,并在实际信道环境下对可伸缩软件无线电平台架构的有效性进行测试,为新型软件无线电平台架构的设计、验证与评估提供参考。
[Abstract]:With the rapid development of wireless communication, on the one hand, the traditional communication equipment based on special hardware has fewer functions and single working mode, which makes it impossible to interconnect between different communication systems, and it is difficult to upgrade. On the other hand, the software radio technology breaks through the limitations of the traditional radio station, and the various functions of the radio can be realized by using software programming. Compared with the traditional special radio station, the software radio technology has higher flexibility. However, the current software radio platform is limited by hardware structure and has low scalability, and the flexibility still needs to be improved due to the limitation of development cycle. In order to solve the above problems, this paper studies a broad network-based scalable software radio platform, which is compatible with traditional special hardware equipment and software radio platform. In order to solve the problem that the expansibility of software radio platform is low and the traditional special hardware equipment is difficult to upgrade and interconnect, a scalable software radio platform architecture based on network is designed in this paper. The designed scalable software radio platform architecture constructs a local area network through a network protocol to realize the integration of heterogeneous transmission devices with different wireless networks, and can plan the number and type of devices in the network according to the actual needs. The expansibility and flexibility of the software radio platform are effectively improved. Furthermore, a network convergence scheme compatible with heterogeneous transmission devices is designed. Transmission equipment includes software radio platform based on general processor, programmable commercial modulation / receiver card, digital broadcast receiver, embedded transmission platform and GPRS network transmission platform. Through the design of scheduling control program, it can be compatible with heterogeneous transmission devices and heterogeneous wireless networks. The test results show that the software radio platform architecture implemented in this paper can quickly build a reliable transmission network compatible with a variety of wireless communication systems. To sum up, this paper designs and implements a network-based scalable software radio platform architecture, and tests the effectiveness of the scalable software radio platform architecture in the actual channel environment, which is the design of a new software radio platform architecture. Verification and evaluation provide reference.
