Dataset containing channel state information (CSI) alongside ground truth data (position tags, timestamps) of a massive MIMO-OFDM system measured with the DICHASUS channel sounder. Measurement parameters and machine-readable file format descriptions are provided in a JSON file (spec.json). Two separate antenna arrays with 64 antennas in total observe a transmitter in a hallway with known 3D model, ideal for raytracing experiments.

Text:

Robot follows a pseudorandom trajectory in the hallway, in the central "lobby" area and in the adjacent hallway towards the west. A metal wall is placed between south wing and central lobby area in south-west orientation, obstructing the LoS of the south wing antenna array. The north wing antenna array has partly LoS and partly NLoS channels. Gain of all receivers is 58dB.

Robot follows trajectories with many direct paths between north wing and adjacent hallway to the west. A metal wall is placed between south wing and central lobby area in south-west orientation, obstructing the LoS of the south wing antenna array. The north wing antenna array has mostly LoS channels, but also NLoS channels in the adjacent hallway to the west. Gain of all receivers is 58dB.

Text:

Robot follows straight-line trajectory in the south wing. A metal wall is placed between south wing and central lobby area in south-west orientation, obstructing the LoS of the north wing antenna array. The south wing antenna array has mostly LoS channels. Gain of all receivers is 58dB. Measurement was terminated early when tachymeter (for ground truth reference data) lost position lock.

Label:

dichasus-dc15.tfrecords

Text:

Robot follows manually controlled trajectory in the central lobby area. A metal wall is placed between south wing and central lobby area in south-west orientation. Robot is close to the metal wall, so channel conditions vary between LoS / NLoS channels for north wing / south wing antenna arrays. Gain of all receivers is 58dB.

The south wing antenna array has partly LoS and partly NLoS channels. Gain of all receivers is 66dB. Tachymeter positions might be slightly less precise (only cm-level) for this file, due to a time synchronization issue (small time lags).
