軟件無線電USRP N300產(chǎn)品概述
USRP N300是一種網(wǎng)絡(luò)軟件定義無線電(SDR),為大規(guī)模和分布式無線系統(tǒng)的部署提供可靠性和容錯(cuò)能力。USRP N300設(shè)備通過引入獨(dú)特的功能來遠(yuǎn)程執(zhí)行任務(wù),如更新軟件、重新啟動(dòng)、工廠重置、自我測試、主機(jī)PC/ARM調(diào)試和監(jiān)視系統(tǒng)健康狀況,從而簡化了無線電網(wǎng)絡(luò)的控制和管理。
RF前端使用AD9371收發(fā)器,這是來自AnalogDevice的最新RFIC技術(shù),提供2X2 MIMO能力,最高100 MHz瞬時(shí)帶寬,擴(kuò)展頻率范圍10 MHz~6 GHz。
?
開源的USRP硬件驅(qū)動(dòng)程序(UHD) API和射頻片上網(wǎng)絡(luò)(RFNoC) FPGA開發(fā)框架減少了軟件開發(fā)工作,并與GNU Radio等多種行業(yè)標(biāo)準(zhǔn)工具集成。用戶可以快速原型化和可靠地部署各種SDR應(yīng)用程序的設(shè)計(jì),如無線試驗(yàn)臺(tái)、遠(yuǎn)程無線電頭、頻譜監(jiān)控等。請注意,USRP N300不是為快速調(diào)諧而設(shè)計(jì)的,因而不適合跳頻應(yīng)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(jìn)行實(shí)時(shí)和低延遲處理,以及雙核ARM CPU用來進(jìn)行獨(dú)立運(yùn)行。用戶可以直接將應(yīng)用程序部署到預(yù)裝的嵌入式Linux操作系統(tǒng)上,或者通過兩個(gè)SFP+端口使用高速接口(如1GigE、10GigE和Aurora)將采樣數(shù)據(jù)注入到PC上。
同步
USRP N300具有靈活的同步體系結(jié)構(gòu),支持傳統(tǒng)的SDR同步方法,如時(shí)鐘參考、PPS時(shí)間參考和GPSDO,從而實(shí)現(xiàn)了高通道數(shù)MIMO系統(tǒng)。此外,USRP N300采用開源的White Rabbit時(shí)序協(xié)議,具有獨(dú)特的基于以太網(wǎng)的同步特性。在沒有g(shù)ps的環(huán)境中,White Rabbit可以實(shí)現(xiàn)長距離的精確基帶同步。有關(guān)更多信息,請參見Ettus Research的“Using Ethernet-Based Synchronization on the USRP N3xx Devices”。
