Measurement of the V2I Massive Radio Channel with the MaMIMOSA Sounder in a Suburban Environment

This paper presents the first V2I channel sounding campaign with the real-time massive MIMO radio channel sounder named MaMIMOSA. This equipment has been jointly developed by ULille (FR) and UGhent (BE) for 5G V2X applications. The system is equipped with a massive 64-antenna array for Tx whereas up to 16 individual antennas can be deployed for Rx. The MaMIMOSA hardware and software capabilities allow to freely adapting the sounding parameters to the investigated scenario demonstrating its versatility and flexibility. Radio channels were measured at 5.89 GHz with 80 MHz bandwidth at the ULille campus using with mean vehicle speed of 30 km/h. In addition to this suburban mobility scenario, Obstructed Line-Of-Sight static radio channels were collected for a roadside to parking setup to study the influence of vegetation. Very preliminary Doppler characteristics are reported from the measured radio channels.
