軟件無線電 USRP E312 產(chǎn)品概述

內(nèi)置電池的USRP E312提供了一個便攜式自主運行的軟件定義的無線電平臺，設(shè)計用于現(xiàn)場部署。來自Analog Devices的靈活的2×2 MIMO AD9361收發(fā)器提供高達56MHz的瞬時帶寬，頻率范圍覆蓋70MHz～6GHz，覆蓋多個感興趣的波段。發(fā)射機和jieshouji前端的射頻濾波器組都提高了選擇性。

基帶處理器使用Xilinx Zynq 7020 SoC來提供FPGA加速計算，并結(jié)合雙核ARM CPU支持的獨立操作。USRP E312包括一套豐富的外圍設(shè)備，如用于位置感知和時間同步的集成GPS接收器，以及用于擴展存儲、I/O和與現(xiàn)有設(shè)備通信的兩個主機USB端口。用戶可以快速原型化和部署具有緊湊的大小、重量和功率需求的移動和嵌入式應(yīng)用程序的設(shè)計。

USRP嵌入式系列平臺使用OpenEmbedded框架創(chuàng)建定制的Linux發(fā)行版，以滿足應(yīng)用程序的特定需求。默認的操作系統(tǒng)預(yù)先安裝了UHD軟件API和各種第三方開發(fā)工具，如GNU Radio。對RFNoC FPGA開發(fā)框架的支持使實時和寬帶信號處理的確定性計算成為可能。

濾波器組

USRP E312包含RX和TX濾波器組。濾波器是根據(jù)用戶頻率動態(tài)選擇的。RX濾波器減少帶外信號的干擾，而TX濾波器抑制諧波。
