Abstract: USRP™ B200/B210, включающей устройства USRP B200 и USRP B210, и серии USRP™ B200mini, включающей устройства, USRP™ B200mini, USRP™ B200mini-i, USRP™ B205mini-i производства компании Ettus Research™, A National Instruments Company. Indoor Positioning System Using TOA Method with USRP Based on IEEE802. Is there a way through either MATLAB or Simulink that I can pull the GPS timestamps from the SDR packets it streams to the PC? I already have the USRP Communications toolbox installed. In our case, 1 or 2 meters antenna cable is used between desk/computer and the window. com 3rd OpenAirInterface Workshop April 28, 2017. tsou@ettus. 72 достигая максимального значения 61129. It supports a radio frequency bandwidth up to 120 MHz. However Compiling GnuRadio on a Raspberry Pi The best bet for most people looking to install GnuRadio on a Raspberry Pi, is to simply do: $ sudo apt-get install gnuradio gnuradio-dev No GPSDO found. 1 Static eTsting Comparison Between GPSDO and Internal USRP Clock
