SIRADEL Railway ray-Tracing MIMO channel samples

This dataset provides synthetic radio channel samples generated by ray-tracing simulation, for use in the study of the Future Railway Mobile Communication System (FRMCS). The data were produced by SIRADEL using their InoWave ray-tracing engine, in the framework of two collaborative research projects: 5G-RACOM and 5G-REMORA. 5G-RACOM (5G for Resilient and Green RAil COMmunications) investigates spectrum-efficient, resilient, and robust designs for FRMCS, covering radio propagation and channel modeling at 900 MHz (band n100) and 1900 MHz (band n101) across various railway operational scenarios, GSM-R/FRMCS coexistence, and hybrid FRMCS network solutions. More information: 5G-RACOM – Franco-German Ecosystem for Private 5G Networks. 5G-REMORA (5G-REalistic radio channel MOdels enabled system evaluation for RAilway environments) supports a "zero-on-site testing" approach for FRMCS deployment, combining realistic railway radio channel characterization from on-site sounder measurements, stochastic modeling, and enhanced ray-tracing, targeting the 900–1900 MHz railway frequency bands. More information: ANR Project-ANR-22-CE22-0015. Dataset content The dataset includes two railway propagation scenarios, both simulated at a 1900 MHz central frequency between a macro-cell base station (BS) located near the track and a dual-polarized antenna mounted on the train rooftop: Montparnasse scenario: An outdoor-to-indoor transition scenario at the edge of the Montparnasse railway station in Paris, covering a 60 m trajectory (30 m outdoor / 30 m indoor) at 20 km/h. Paris scenario: An urban propagation scenario in the south of Paris, covering a 163 m trajectory at 100 km/h, including scattering effects from 22 metallic catenary pylons along the track. Each scenario is provided as a CSV file containing, for each simulated user-equipment (UE) position along the train trajectory, the set of ray-traced multipath components (delay, Doppler shift, azimuth/elevation angles of departure and arrival, and complex path amplitudes for all four V/H polarization combinations), along with UE position, timestamp, and line-of-sight/obstruction status. The channel data is provided as raw propagation output — no transmit power, antenna pattern, or signal bandwidth is applied. The complete CSV field definitions and coordinate/angle conventions are documented in the accompanying file SIRADEL railway channel data format – v1.3.pdf.
