Calibration Procedure

Calibration procedure is using custom made UHD based program to generate sine wave on a transmitter and collect signal strength measurements on a receiver. This program is available in usrp-calibration.ndz image. To put the image on the set of arena nodes and turn them on, execute the following two OMF commands:

  omf load -t system:topo:dsc-arena -i usrp-calibration.ndz
  omf tell -a on -t system:topo:imaged

The short calibration procedure is OEDL based experiment that operates on the latest set of imaged nodes. It loops over the set and in each iteration uses a single node as a transmitter and all other nodes as receivers. It displays the set of calibration matrices for the various DSC topologies. To get the calibration results:

user@console.grid:~/# omf exec system:exp:dsc-calibration
