一种基于USRP的5G认知网络系统架构及其方法
摘要：
一种基于USRP的5G认知网络系统架构及其方法，USRP通过以太网与主机计算机PC相连接；所述主机计算机PC中包括LabVIEW软件平台和NI USRP软件套件，NI USRP软件套件在LabVIEW中增加了NI-USRP驱动程序，所述LabVIEW软件平台中的程序通过NI-USRP驱动程序与所述USRP进行交互；LabVIEW软件平台中的程序包括认知程序，所述认知程序包括接收无线信号和发射无线信号模块、频谱感知模块、确定发射频率模块、音频信号FM调制模块以及FM信号解调模块。可以实现授权用户和认知用户对频谱在不同时刻、不同频段上的充分利用，同时避免了对授权用户的干扰。
摘要（英）：

The invention discloses a 5G cognitive network system architecture and a method thereof based on a USRP. The USRP is connected with a host computer PC through Ethernet; the host computer PC comprisesa LabVIEW software platform and an NI USRP software suite; the NI USRP software suite adds an NI-USRP driver to the LabVIEW, and the program in the LabVIEW software platform interacts with the USRP through the NI USRP driver; and the program in the LabVIEW software platform comprises a cognitive program, and the cognitive program comprises a receiving wireless signal and transmitting wireless signal module, a spectrum sensing module, a transmitting frequency determination module, an audio signal FM modulating module, and an FM signal demodulation module. Thorough use of the spectrum at different times and frequency bands by a secondary user and a primary user can be realized, and interference on the secondary user can be avoided.
