軟件無線電USRP N300產品概述

• • USRP N300是一種網絡軟件定義無線電(SDR)，為大規模和分布式無線系統的部署提供可靠性和容錯能力。USRP N300設備通過引入的功能來遠程執行任務，如更新軟件、重新啟動、工廠重置、自我測試、主機PC/ARM調試和監視系統健康狀況，從而簡化了無線電網絡的控制和管理。

    
    

    RF前端使用AD9371收發器，這是來自AnalogDevice的RFIC技術，提供2X2 MIMO能力，100 MHz瞬時帶寬，擴展頻率范圍10 MHz～6 GHz。

    開源的USRP硬件驅動程序(UHD) API和射頻片上網絡(RFNoC) FPGA開發框架減少了軟件開發工作，并與GNU Radio等多種行業標準工具集成。用戶可以快速原型化和可靠地部署各種SDR應用程序的設計，如無線試驗臺、遠程無線電頭、頻譜監控等。請注意，USRP N300不是為快速調諧而設計的，因而不適合跳頻應用。

    
    

    基帶處理器

    
    

    基帶處理器使用Xilinx Zynq-7035 SoC提供大容量用戶可編程FPGA進行實時和低延遲處理，以及雙核ARM CPU用來進行獨立運行。用戶可以直接將應用程序部署到預裝的嵌入式Linux操作系統上，或者通過兩個SFP+端口使用高速接口(如1GigE、10GigE和Aurora)將采樣數據注入到PC上。

    
    

    同步

    
    

    USRP N300具有靈活的同步體系結構，支持傳統的SDR同步方法，如時鐘參考、PPS時間參考和GPSDO，從而實現了高通道數MIMO系統。此外，USRP N300采用開源的White Rabbit時序協議，具有的基于以太網的同步特性。在沒有gps的環境中，White Rabbit可以實現長距離的精確基帶同步。有關更多信息，請參見Ettus Research的“Using Ethernet-Based Synchronization on the USRP N3xx Devices"。
