The current model can operate from 1.3 GHz to 10 GHz. Two frequencies are currently available, 1.35 GHz and 5.89 GHz with a bandwidth of 80 MHz. The sounder is based on FPGA digital processing coupled with a computer for data recording.<br \/>\nMaMIMOSA is based on space-frequency multiplexing, which gives great flexibility in tone and antenna allocation. This channel sounder belongs to the new generation of systems based on software-defined radio design. The architecture of the proposed approach has been designed with the greatest possible flexibility, opening up a wide range of applications. In addition, the channel sounder has been designed to avoid cumbersome post-processing:<\/p>\n<p>i) the Tx signal is pre-processed to include the non-linearity of the Tx and Rx chain,<\/p>\n<p>ii) thanks to the FPGA's high sampling rate, a true baseband digital signal is transmitted to the RF chain without I\/Q alteration,<\/p>\n<p>iii) the output file gives the transfer function 4.Ntx.Nrx in a versatile binary format. Finally, the sounder's power consumption is low and can be powered by a 24 V battery with an autonomy of 8 hours.<\/p>\n<\/div><\/section><br \/>\n<section  class='av_textblock_section av-1w3p5l1-f0e82905def5c21cb7979c3343bf3beb'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><blockquote>\n<p>Contact: Pierre Laly<\/p>\n<\/blockquote>\n<\/div><\/section><\/p><\/div><\/div><!--close column table wrapper.
