28 GHz V2I measurements on highways

In this dataset, 4 radio channel measurements at 28 GHz are presented. These have been captured in two different spots of a highway with a fixed Tx and a mobile Rx onboard a car, emulating a V2I link. The Tx was placed both on the roadside (3 measurement runs) and on an overpass (1 measurement). Each run consists of around 4.29 s of continuously captured channel impulse responses (CIRs), with a channel sampling period of 65 μs and a delay resolution of 2 ns. The channel sounder used the pseudorandom binary sequence 11 (PRBS11) to excite the channel and extract multipath characteristics, using two pre-synchronyzed rubidium standards in order to keep synchronization between Tx and Rx clocks. Nonetheless, no absolute delay or amplitude synchronization has been performed. The dataset can be processed in order to extract wideband channel characteristics.
