Fyoris: Full-polarimetric V2I MIMO channel sounding data sets @2.53GHz in urban environment

Seven measurement runs, selected from a measurement campaign in Bonn, Germany, are provided. The environment is urban, the context is V2I from an elevated base station, the set-up is fully polarimetric MIMO with two 16 dual-pol element stacked circular arrays, configured as two circular rings of 8 elements each. The frequency is 2,53GHz, the bandwidth 20MHz. For easy access of relevant quantities, data and meta data are stored in HDF5 format. For aiding interpretation of the data, full Tx and Rx array characteristics are included.

Introduction §

Content and Format §

The format of the data is described in the respective entries in Documentation. We provide the measurement data in sampled frequency domain in FrequencyResponses.h5 and the associated antenna array calibration data as ArrayTx.h5 (TX) and ArrayRx.h5 (RX) respectively.

Applied Processing §

The data was processed in such a way that the frequency response of the measurement device was removed as well as possible by means of appropriate back-to-back calibration and equalization. What has not been removed is the angle- and polarization-dependent influence of each antenna port. This is due to the fact that these change depending on the direction of departure and direction of arrival of each individual propagation path. Hence, the deembedding of the antenna arrays can only be achieved by extracing the complete propagation information from the measurement data.
