Channel Emulation for OTA Test Based on a Simulated Channel in a V2V Drive Scenario

This paper introduces a novel approach for transitioning from high-granularity Ray-Tracing (RT) channel simulations to channel emulation, accompanied by an over-the-air test. The RT simulation is performed on a Vehicle-to-Vehicle (V2V) communication drive scenario generating basis for channel emulation in a channel emulator. The channel simulation, and the accompanying channel emulation, also enables inclusion of antenna radiation patterns of both transmitting as well as receiving antennas in the V2V setup. Validation procedures are executed to verify the proposed method, which finally is used on a set of real radio units and the experimental results are presented.
