Abstract: The application relates to a device and to a method for detecting a Dedicated Short Range Communication (DSRC) signal in a motor vehicle, in particular having a module with a “C2X” communication system and/or “Car2Car” communication system of a motor vehicle, wherein after amplitude demodulation of a received signal, one or more properties of the received signal are examined by a protocol detector.

Abstract: A method for testing a vehicle-to-X communication module by means of a diagnostic device as well as an associated vehicle-to-X communication module and an associated diagnostic device. During a test mode messages are exchanged between the vehicle-to-X communication module and the diagnostic device, and evaluated in order to detect errors.

Abstract: Detection for localizing at least one particle moving in a flow includes emitting a transmission signal by a transmitter, and receiving a reflected reception signal. The reflected reception signal is frequency and phase modulated in comparison with the transmission signal. The reflected reception signal is convolved with at least one kernel representative of a conjugate estimated channel pulse response. A reconstructed particle position function is formed, and the position of the particle is determined from the reconstructed particle position function.

Abstract: A diversified antenna system is suitable for vehicle-to-vehicle or vehicle-to-infrastructure communication. The antenna system has a first antenna arrangement and a directional antenna arrangement. The first antenna arrangement has a blind spot from which it cannot receive a signal. The directional antenna arrangement is configured to receive signals from the blind spot of the first antenna arrangement. A vehicle is provided with such an antenna system and communication is effected between vehicles or between vehicles and infrastructures.

Abstract: The present disclosure relates to communication systems for a motor vehicle. In some embodiments, a communication device may provide, for example, car-to-car communication (vehicle-to-vehicle communication). A communication system for a motor vehicle, the system may include: a transceiver unit for generating transmission signals where at least two of the transmission signals differ in their signal power; a cable to transmit the transmission signals to an antenna via a controllable amplifier device; a power detector device capturing a respective power value correlated with a power of the transmission signals at a tapping point between the cable and the antenna; and a control device controlling the amplifier device on the basis of the captured power values. The transceiver device generates at least one of the transmission signals with a predetermined reference power. A reference value describing the reference power is permanently predefined in the control device.
