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>- The bench includes a wide range of test systems and software that can provide a flexible and powerful environment for carrying out key tests in the telecommunications field up to 60 GHz, such as :<br \/>\nReal-time characterisation of a complex transmission and\/or reception system, from baseband generation to RF transmission.<br \/>\n- Real-time characterisation of a transmission\/reception system, from demodulation to data recovery, with options for analysing the integrity of the RF signal at each stage of the channel (EVM, channel power measurements, occupied bandwidth, modulation accuracy, etc.), the digital signal (BERT, PER, eye diagrams, jitter measurements) and mixed signals.<br \/>\n- Characterisation of link robustness in relation to real-time RF channel emulation, interference analysis.<br \/>\n- Physical testing of interoperability in heterogeneous sensor networks.<br \/>\n- Testing the non-linearity of an amplifier on the communication channel and hard\/soft correction.<br \/>\n- Frequency and phase synchronisation test.<br \/>\n- Testing the accuracy and stability of the clock.<br \/>\n- Optimise the size of transmission packets.<br \/>\n- Optimise the size of the synchronisation preamble.<br \/>\n- Measure component temperature drift and the impact on the transmission.<br \/>\nCertain measurement techniques can be used by the CHOP group for THz communications.<\/p>\n<div id=\"attachment_63686\" style=\"width: 505px\" class=\"wp-caption alignright\"><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/sigmacom_3.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-63686\" class=\"wp-image-63686 size-portfolio\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/sigmacom_3-495x342.jpg\" alt=\"\" width=\"495\" height=\"342\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/sigmacom_3-495x342.jpg 495w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/05\/sigmacom_3-18x12.jpg 18w\" sizes=\"auto, (max-width: 495px) 100vw, 495px\" \/><\/a><p id=\"caption-attachment-63686\" class=\"wp-caption-text\">Characterization of a real-time communication<\/p><\/div>\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.
