More than 1.3 million people die on the roads every year. Safe, automated driving supported by Vehicle-to-Everything communications, or V2X, will improve driving comfort and has the potential to save lives by preventing many traffic accidents.
Well-established vehicle sensors, e.g. radar sensors, cameras and tachometers, already provide information about distances to surroundings and velocities, but sharing information from the vehicle to everything also allows knowledge of critical traffic situations and collisions so that the driver or the car can initiate countermeasures to avoid accidents or create a better traffic flow.
Vehicle-to-vehicle (V2V) communications systems require a stable wireless link to maximize the throughput of information, which increases driver safety. To ensure a good wireless link, receivers must be able to detect signals even under the worst conditions, e.g. low signal-to-noise ratio (SNR), poor error vector magnitude (EVM) and heavy fading. Replicating these conditions in the lab requires high-performance test equipment capable of generating/analyzing the V2X signals, the required fading conditions and satellite signals for highly accurate positioning.
