These integrated hardware and software solutions enable rapid prototyping of wireless communication systems. NI USRP transceivers can transmit and receive RF signals in multiple bands. The USRP hardware architecture integrates RF analogue front-ends (high-low conversion, filters, amplifiers), an RF I\/Q modulation-demodulation stage, ADCs and DACs, a processor or FPGA connected by cable to a host computer (PC or PXI chassis) to send and receive correctly formatted baseband I\/Q data. USRPs are programmed using the LabVIEW development environment. This solution offers great flexibility for software radio prototyping and communications research.<\/p>\n<h5>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-13ewzjw-6-da957843d9fdb7752868995c228d43e7\">\n.av_font_icon.av-13ewzjw-6-da957843d9fdb7752868995c228d43e7{\ncolor:#800000;\nborder-color:#800000;\n}\n.av_font_icon.av-13ewzjw-6-da957843d9fdb7752868995c228d43e7 .av-icon-char{\nfont-size:30px;\nline-height:30px;\n}\n<\/style>\n<span  class='av_font_icon av-13ewzjw-6-da957843d9fdb7752868995c228d43e7 avia_animate_when_visible av-icon-style- avia-icon-pos-left avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue871' data-av_iconfont='entypo-fontello' ><\/span><\/span> Applications<\/h5>\n<p>USRP equipment can be used for a wide range of applications.<br \/>\n- Dynamic access to the RF spectrum and real-time recording of signals over a long period.<br \/>\n- Research into the PHY and MAC layers for robust radio links.<br \/>\n- Creation of customised transmission or reception protocols.<br \/>\n- Building multi-standard communication gateways<br \/>\n- Integrate the USRP into a standard radio communications network to test new wireless algorithms (TDD, FDD) to improve communications.<br \/>\n- Test the channel coding or source coding blocks<br \/>\n- Simulate channel degradation and check the impact on transmissions.<br \/>\n- Implementation of MIMO technology<\/p>\n<p><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/Sans-titre-13.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-63693 aligncenter\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/Sans-titre-13.jpg\" alt=\"\" width=\"434\" height=\"273\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/Sans-titre-13.jpg 434w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/Sans-titre-13-300x189.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/Sans-titre-13-18x12.jpg 18w\" sizes=\"auto, (max-width: 434px) 100vw, 434px\" \/><\/a><\/p>\n<p><strong>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-qawvnx-c6d7a48945715fae5b55f5b15d0481bc\">\n.av_font_icon.av-qawvnx-c6d7a48945715fae5b55f5b15d0481bc{\ncolor:#761713;\nborder-color:#761713;\n}\n.av_font_icon.av-qawvnx-c6d7a48945715fae5b55f5b15d0481bc .av-icon-char{\nfont-size:30px;\nline-height:30px;\n}\n<\/style>\n<span  class='av_font_icon av-qawvnx-c6d7a48945715fae5b55f5b15d0481bc avia_animate_when_visible av-icon-style- avia-icon-pos-left avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue860' data-av_iconfont='entypo-fontello' ><\/span><\/span> HIGHLIGHTS<br \/>\n<\/strong><\/p>\n<p>- Main physical characteristics of the USRP<br \/>\nThe USRPs are equipped with a 10 MHz OCXO (Oven Controlled Crystal Oscillator) reference clock, which complies with the GPS standard.
