摘　　要：针对通信技术更新迅速,导致LTE等无线通信设备更新价格昂贵,从而提出使用通用软件无线电开发平台XSRP实现TD-LTE物理层协议实验,设计并实现了TD-LTE物理层协议的收发通信实验。设计的实验中XSRP和上位机通过以太网口传输数据流,基于软硬件协同,上位机利用Matlab负责获取处理基带数据流和配置XSRP射频参数,XSRP负责数据实时处理和射频收发。通过实验表明:基于XSRP通用平台的收发天线,在真实信道环境条件下实现了多机通信,真实模拟了TD-LTE物理层协议的实现过程,接近现实的通信系统,为移动通信系统协议栈的原型开发与验证提供了范例。In view of the rapid development of communication technology,the update of wireless communication instruments such as LTE is expensive,an experimental design for TD-LTE physical layer protocol using XSRP general software radio development platform is presented,and the implementation process of the transmitter and receiver experiments of TD-LTE physical layer protocol is designed in this paper.Based on the idea of hardware and software cooperation,in this design the data stream is transmitted through ethernet port between XSRP and computer.Computer is used for acquiring and processing baseband data stream and configuring the radio frequency(RF)parameters of XSRP by using Matlab.XSRP is used for real-time data processing and transmitting and receiving the RF signals.Experiments results show that compared with the traditional software simulation and verification,the XSRP general platform creates the conditions for the experiment to use the real channel transmission environment,which can realize the multi machine communication,can simulate the realization process of TD-LTE physical layer protocol in a real way,and is very close to the real communication system.It provides an example for the prototype development and verification of the mobile communication system protocol stack.
